Gate assignments are made shortly before boarding and each letter dedicated terminal group is separated by a long walk or a crowded rail ride. The metro ride between the terminals and the city can be complicated if you go in with no research. We consider ourselves capable people but Londons rail system is a mess to get a grasp of.

Prepare for the unexpected. It’s a long flight and anything can happen. Have some snacks and drinks with you. And other emergency items you may need.

Heathrow is a large busy airport that requires a lot of walking.

People have to make sure they have plenty of time (2 hours minimum) if they need to change terminals. Heathrow is a monster airport, it's giant, so if you want to shop or eat or just look around, you need more than 2 hours between flights. Otherwise, it's great, the security was fast but thorough. I loved that I did not have to remove my shoes and the employees were patient and polite, not like at JFK. The shuttle buses are annoying, but at a huge airport like Heathrow, it's a must. The drivers of the shuttles are crazy, they don't care if people are falling down or not, they drive aggressively. However, people cannot fall down because the buses are packed to the gills. So, instead of shuttles, a looping airtrain would be a much more convenient and probably faster way of connecting the terminals, just like at JFK. The frequent flights between London and New York are much appreciated.

London makes you take out every single toiletry even below 100ml and if they don’t all fit in one tiny bag, they make you throw it away. Check everything in your checked luggage!

Even if you have a long layover, be prepared to travel a long distance to your gate once it gets announced. Do not delay in heading to the gate. Be prepared for a very crowded airport experience.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

The crew should demonstrate flexibility by moving a screaming infant to its own seat with 1 parent

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

I was pleasantly surprised and enjoyed the services of the airline since flying is not my favorite thing. My goal was to be with my brother's family in Manchester after his death. All staff was helpful, the food appreciated since I selected an overnight flight. Every aspect of the experience was comforting. I plan to return to Manchester in order to attend my brother's funeral in October and hope that I am able to find a reasonable priced flight. Thank you

Very good except for the boarding process which was more hectic than it should have been

All of my Aer Lingus flights were delayed. The seat I purchased with extra leg room was exactly the same as my previous seat that was free. I would appreciate my money back.

Not satisfying due to loss Luguage for 4days. Damage Luguage that had no way to fill up a report for and me as a client to spend more money and time to replace it. Thank you for soliciting my opinion, but it was unfortunately a very disappointing experience. Stephanie Zvi

The seat spacing was good. The food, not so good... typical airline food. 😕

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

The friendly staff. They kept time. Was suprised to get some drinks.

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

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.

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.

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.

I loved the ability to upgrade my seat which was worth it. The large seat and ability to recline made it comfortable to fall asleep. My only two complaints were entertainment (movie selections were old) and approx 30 mins before landing the crew started to collect the blankets despite the cabin air temperature remaining cold. Maybe wait for passengers to get off the plane before collecting the blankets.

Very much dislike: Airline requires check-in at the Airport Airline does not work with TSA PreCheck

The crew was unfriendly front check-in. The filth in the plane was so disappointing. I could smell dirt and looked up and there was literally dirt that was blowing in through the air. Old food on the seat back tray in front of me so I didn’t use it. No toilet paper in the bathroom and scum/old dirt next to the seats.

Boarding was easy. Provided drinks and snacks. Good aircraft and staff

Jetblue provided a very good service during the flight, the plane in a very good condition, the crew is professional, everything was on time. That's it!

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

My encounter with the entertainment services provided on board was moderate; the functionality of the Wi-Fi connection was either sluggish or nonoperational, while the display screens were antiquated and suffered from poor visibility. On the positive side, the cabin exuded a sense of expansiveness, and the crew exhibited amiable and accommodating behavior throughout the journey.

My experience with JetBlue was fantastic! The service was top-notch, the flight was smooth, and the staff were friendly and helpful. I would definitely fly with them again.

There was only internet service for the last hour. Other than that is was a great flight. Good Crew and landed a head of time.

Best Thing flight took less time than programmed, quick entry and exit. Recommended!

No entertainment, no WiFi, not great seats. Crew was good.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

After boarding we were waiting in the plane for more than one hour to take off without AC with very high temperature inside

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.

British Airways did a great job and the entire crew was punctual and polite; dignified and delightful!

Boarding is not controlled as groups called was not enforced

I never was able to take this cancelled flight…all flights from Zagreb were cancelled at 3:30 AM of departure day 9/8!

The crew was very attentive and kept busy serving a variety of treats!

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again

The crew were great. The comfort and food was terrible, worst I have experienced in recent times and I fly a lot. It was like a refrigerator in the back and even with 4 blankets could not get comfortable. Seats are very tight and with the electronic box under the aisle seats, there was no legroom. BA did a bait and switch on the price, lowballing the price and then requiring add ons, like paying for a checked bag. While common on domestic flights, I have never had to pay for the first bag flying intercontinentally. Also, no “choice “ of seating at check in. There was not a single other free option. I could pay to choose a seat in the same row. I have never had this happen either.usually, at check in, you have a choice (I.e. free) on other airlines of what is not occupied in your section. I will never never fly BA again. Too bad, since the crew were some of the best with the best attitudes I have experienced.
