Was a really good flight and so fast always try to get the first 5 road if you can

Almost as usual, half an hour take off dilay, on the other hand - the checked in baggage arrived as magic super quickly. By the way - why do you ask to rate the food and entertainment on flights without them? at least offer the option of "Not Relevant" or similar...

Not constantly changing the price DURING a booking. Felt like bait and switch.

All very smooth airside. Check-in counters were understaffed. The wait is too long. Only two, then three counters were open. Waiting time of 35 minutes is too long. Pls review your rota.

Very fast boarding. Crew members were super nice. I loved it!

My luggage got lost and until today there is no solution to the problem. It's still missing

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

The flight attendants were friendly and professional. I asked to change my seat and the flight attendant was accommodating. We experienced a short delay due to the late arrival of the plane. However, the onboarding and disembarking process was efficient.

The passport control process in Lisbon ranks as a 1 on a 1 to 5 scale. Terrible. In line 2 hours and still missed our first flight. Next day, 1.5 hours but we made the flight. The Business Class food was poor. Unidentifiable. Not tasty at all. Unacceptable in BC. Attendants were adequate. Flight left late and arrived late. After this trip, we will not be flying TAP nor will we be connecting through Lisbon.

The food left a lot to be desired. The crew was great

No difference between business class and normal same seat everything same, waste of money

They allowed me to book the flight, which took quite an effort to find the best option for us, and then 2 months later, cancelled it because they didn't think 90 minutes was enough time to get between connections. Why let me book the flight in the first place? I am somewhat disappointed in Kayak and will be choosing other options in the future

Delayed departure Madrid to Lisboa and my luggage no arrived

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.

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

Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

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

Very cheap airline, not worth the price. And they almost lost my luggage at JFK during a direct flight. I can't believe I paid that much money for a horrible 'premium economy' flight. Just fly economy on the cheapest end; premium economy is no different. Very very poor.

Boarded in group three at Barcelona, which meant going from a gate outside onto a bus to ride across the airport to a plane waiting on the tarmac. When we arrived at the plane, crew behavior told us something was wrong. Bus driver would not let us off for almost twenty minutes, despite being crammed shoulder to shoulder. Eventually, we got onto the plane, but were then told that someone “forgot” to refuel the plane and the truck to do so had not arrived. We departed late enough that we missed our connecting train in NYC, which was the last train of the evening, so we had to stay awake all night in the passenger waiting area of Amtrak’s Penn Station, which was almost impossible to get to because the station was now closing, as it was after midnight. We had to haul four suitcases a few blocks on city streets in the rain to get to the one remaining open entrance to Penn Station. We ended up being up for 36 hours straight because someone couldn’t do their job. Never, ever again would I fly this airline.

All four segments of my trip on Iberia were late for various reasons. No apparent effort to stay on schedule. Never flying Iberia again.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Without any prior warning, I was seated in a row just in front of an exit row (27F), and I had no idea that my seat would not recline. However, the person in front of me did recline her seat, reducing my space. And because I could't recline to regain some space, it was my WORST flight ever.

Puddle-hopper. Quick-ish flight. Don’t expect to have much/any in-flight entertainment (movies/TV, etc).

Flight cancelled, lost a day of travel where we were trying to meet friends we couldn't meet. Iberia website is very difficult to navigate and has lots of dead links. If you do not speak Spanish it is even harder. Tried communicating on their WhatsApp and that was also close to impossible. We were told we'd be compensated 150EU's for this cancelled flight but there is no avenue towards rectifying this issue. I've had to take it up with my credit card to contest the charges and not pay for a flight that didn't happen but doubt I will ever be reimbursed for my two Ubers to the airport where we never even departed or the 150EU's we were told we would receive. I would never fly Iberia again. Clown show.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Terrible. Boarding was a mess. We were assigned middle seats and separate just to induce us to pay for better seats. Cabin luggage was checked in while space remained on the overboard lockers. I think they don't really care about the customer.

The trays weren’t wiped. They still had food from last passengers

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Great flight, departed only 10 mins behind schedule off the aircraft and through security in less than 15 minutes. Love flying from Cardiff so easy a quick from entrance to duty free in less than 10 minutes 😀

Well... Our flight departed with more than 3 hours delay from Beauvais.

Great flight very short… no food drink or tv but too quick to matter… I would recommend.

I haven't had a ok flight with Ryanair in so long!

The flight was delayed by over an hour which seriously disrupted my plans in Milan.

The workers checking passengers from the boarding gate stole money from people whose luggage was perfectly fitting inside the carry-on sizer.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

I was charged at the gate for bags I had already paid for. There was no other option. I am trying diligently thought easyJet website but making no progress HELP!

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Boarding great. Didn’t eat or drink so can not comment.

The pilot did everything possible to make up the 35 minute delay. His communications were honest, prompt and positive throughout.

Staff were lovely. Seats could be wider/ more comfortable and late taking off
