Flight from London Gatwick Airport to Miami

FAQs - booking Florida Keys flights

  • Which airports do I choose for booking a flight to Florida Keys from Scotland?

    There are no direct flights to Florida Keys or other nearby airports from Scotland. Travellers will thus have to reckon with a flight with two stopovers – most likely one in London and one in Miami. The best airport in London for a stopover is London Heathrow (LHR), because it’s the one with the most routes from Scotland: you can directly fly from Aberdeen (ABZ), Inverness (INV), Edinburgh (EDI), or Glasgow (GLA). The second stopover on this route will probably be Miami International, followed by a short connecting flight (55min) to Key West International Airport.

  • Which cities in England can I fly directly to Florida Keys from?

    There are no direct flights to Florida Keys from England, but there are direct flights to Miami International, which is the closest international airport. Both London Gatwick and London Heathrow are served by regular flights to Miami. If you want more options when it comes to airlines, search for a flight to Florida Keys that departs from London Heathrow.

  • Which airports are best for a flight to Florida Keys from Northern Ireland?

    Passengers travelling to Florida Keys from Northern Ireland need to factor in a first stopover in London Heathrow or London Gatwick. Heathrow has the most options when it comes to airlines serving Florida, and both Aer Lingus and British Airways operate direct flights here from George Best Belfast City Airport (BHD). If you prefer to fly out of Belfast International Airport (BFS), easyJet operates direct flights to London Gatwick, but keep in mind that here you'll have fewer options for airlines when it comes to your connecting flight to Florida.

  • Which airports should I choose for a flight to Florida Keys with a stopover in Orlando?

    Orlando International Airport (MCO) has connecting flights to Key West International, operated by regional airline Silver Airways. Virgin Atlantic, British Airways, and Norwegian operate regular flights from London Gatwick to Orlando International Airport. If you’re flying from other airports in the United Kingdom, there are seasonal flights from Glasgow, Belfast International Airport, and Manchester International Airport (MAN).

  • How does KAYAK find such low prices on flights from the United Kingdom to Florida Keys?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United Kingdom to Florida Keys.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United Kingdom to Florida Keys?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United Kingdom to Florida Keys is likely to change within 7 days, so travellers know whether to wait or book now.

  • What is the Hacker Fare option on flights from the United Kingdom to Florida Keys?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly from the United Kingdom to Florida Keys with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United Kingdom to Florida Keys?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United Kingdom to Florida Keys up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • What is the cheapest day to fly to Florida Keys?

  • Key West Airport receives mainly from other American destinations, so when looking for flights to Florida Keys from the United Kingdom account for at least one stopover in New York or Orlando.
  • Passengers looking for the least number of stopovers possible and more options when it comes to airlines can book a flight that lands in Miami International Airport (MIA) or Fort Lauderdale-Hollywood International Airport (FLL) instead. The farthest island on the archipelago, Key West, is around a 3h 30min drive from Miami, and also a 3h 30min drive from Fort Lauderdale via US Highway 1.
  • If you’re travelling to Key Largo, keep in mind that this island doesn’t have an airport with commercial flights. The closest airport is Miami International, which is just over 1h away by car.
  • Citizens from the United Kingdom don’t need a visa to enter the United States and can apply online for an Electronic System for Travel Authorisation (ESTA) under the Visa Waiver Program when visiting the Florida Keys. This allows British citizens to stay in the country for up to 90 days for tourism. When booking your flight to Florida Keys, keep in mind that you’ll need both a valid passport and ESTA confirmation to travel.

Airline reviews

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We had an unfortunate experience where we had to leave the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason given was that a passenger felt ill and had to cancel their plans and therefor their luggage had to be found and removed.

We’ve used VA before many times the experience is always been good they have lovely staff and the food is always delicious.

Everything about the flight was amazing from check in to boarding entertainment was okay food we didn’t try.

Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that

Unexpectedly was surprised with the space on flight in economy and the price.

I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.

Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.

The movies were super old. The crew did not offer WATER???? 5 hours os flight and did not get WATER? Norse is the worst company I ever used and never will use again.

Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!

We flew one way from Gatwick, London to JFK NY For 2 people $1200 and no food offered not even water. You had to buy food. Norse advertises as a low fare transatlantic airline, they may want rethink that. Crew, flight was fine. Ironically we flew American from JFK to Heathrow for $1000 (2people) and included food and drinks.

Longest check in line I have ever seen- brutal and airline personnel hustled me about the size of my bag even though I showed them that it measured exactly to the measurements posted on their site. Just super annoying- I get it - it’s a budget airline and you get what you pay for. Most of the flight were young people who seemed to have never experienced international travel. It’s worth paying for a seat otherwise you will be uncomfortable.

We flew premium on the way TO London but went back to economy for this flight. The differences I note here may be colored by changing service. The crew was professional and polite but cold on this flight and class of service. They seemed to want to have as little to do with us as possible, beyond providing the basic services in economy. The aircraft was still good though, and the pitch was about as tight as expected - manageable but no extra personal space to spare. Overall I would certainly fly Norse Atlantic again, given the opportunity.

The crew really made the difference. Some of the friendliest cabin crew I have ever encountered- they seemed genuinely happy to be there, and took pride in their airline and aircraft. The Dreamliner was quieter than legacy aircraft and while meals weren’t to our preference, they were at least something to keep us going!

Terrible flight attendant attitude. Average 3-star hotel employee has better hospitality skills. Business class seats are literally a joke. TAP executives should ride business class in other airlines to develop some rudimentary sense of what business class is.

I’ve never had worse food in business class ever!

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

Do you have a bad service And And treat customers terrible

Very pleasant flight, crew was very nice. The flight was really smooth, big plane. The seats are kind of close together, so comfort was just OK. The boarding process on the way back to New York was a little chaotic. It took a long time.There were no announcements, no loudspeaker just one staff yelling out of instructions and a lot of people crowding in before their term to board. So that could really be improved a lot.

The crew was very nice. The food was good. The entertainment on the way back to Miami wasn’t as good as the flight over. I wanted to watch Wicked but on the way over from Miami to Lisbon but the screen didn’t work. On the way from Lisbon to Miami Wicked wasn’t an option. Liked the option to check out overhead carry on with our checked luggage Overall the flights were very good. I would fly TaP again

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.

Fantastic! Great seats! Friendly staff! Amazing selection of shows and movies! Smooth ride! I don’t know what more I could have asked for honestly. They made flying a breeze this time around.
