We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

Friendly staff, It was the first flight out for our plane, so had to be deiced from the frost. Only delayed a few minutes,

reliable, relatively relaxed, helpful and kind staff and clean airplanes. No need for more.

reliable, relatively relaxed, with helpful staff in all 8 flights we had on this trip. They are solid even though we did not have special seating or status for the flights.

Very poor ! Latam is really excellent in mistreating its premium passengers and their family. They should go out of business for good.

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.

I wish they could put the pre-tsa check on the tickets or global entry.

very good all round. staff, food, entertainment, punctuality all very good

The cabin crew were great very helpful and accommodating. We had a fellow passenger throw up next to us. The flight crew did an amazing job cleaning up and reseating us. We did question as to if he should have been let on the flight as his condition was likely self imposed.

Great flight, short and good attention. Didn't took any food so can't say thing about it

A 13 hour flight with no food apart from what they offered from a menu you had to pay for. On top of that, there were no blankets, so during the flight when the cabin temperature dropped, everyone was very cold. Neither of these things were highlighted at the time of booking. This is the worst long-haul flight I’ve ever encountered.

They didn't even give us water, everything was sold

They should at least offer water like other airlines, which seems like a humanitarian gesture to me

They gave me an upgrade but charged me for my bag. I felt abused because this had never happened to me before with an upgrade with another airline.

Well. It is a no frills airline. Annoying is that even for the long-haul everything has to be paid for separately. Once you add up the extras the flight is getting to expensive. Then one might as well fly with a legacy carrier which provides far better comfort. Changing flight at MAD airport is a nightmare. The worst airport in the world. Poor signposting, poor passport control, poor security check and long queues. I had 2h transfer time and spend in queues almost 1.5h

All flights with Air Europa you arrive late to the connections of other flights, I missed my train, I had to pay for my train again, the crew are antisocial, you are paying for a service, it is not free, thanks to the travelers they are there, it is the last time I fly with them,

Terrible experience - we won’t be flying with Air Europa again

The crew was not kind , just doing their job but very cold people

The insanely long lines at customs were chaotic and stressful. They also created a lot of stress among passengers. Including fights and threats. The hot food I purchased was cold, barely edible. The check in staff and crew were nice and the pilot good but the overall experience was very disappointing. Passengers were still insulting each other upon arrival.

No frills airlines. Tickets were reasonably priced for a short-term booking. But comfort is a big issue.

It was just okay. They overcharged me for a checked bag because I didn’t know it wasn’t included in the airfare.

The media system is so inreliable, it keeps freezing and restarting at the begonning. Old planes with an old entertainment system makes a long flight very boring

Terrible experience. Should be a short simple flight from San Francisco to Palm Springs. Disgusting insult that United Air doesn’t have a cabin crew ready to receive a plane that’s already an hour plus late in departure. Lots of misinformation along the way from cockpit and crew. Definitely unimpressed with both union and management.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Using the media screen in economy class is a disaster

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

Great crew dealing with the most unprepared family with a million kids and zero sense.

The staff was not at pleasant as those on the first leg of our trip.

My first two flights were late. I missed my last flight. The next flight was not until the next day Seating on large plane was uncomfortable. In the center row, there are posts that do not allow you to spread your legs. The entertainment center did not respond well. . Food was okay. Though there was much confusion about where the special meals that. People ordered(not me) went

Upgraded to business class and it was worth every dollar! The connection in Denver was way too tight time wise and going through customs there plus re-visiting security screen again caused me to miss my connecting flight. KAYAK should not allow that tight of connection on international flights.

I will not fly them again. Late flight ( no communication as to why)… no one even remotely working to help those with connections that are very narrow off the plane in a hurry … NO ONE understood how to move … and 1/2 the plane was running to connections. I missed mine. Total pain in the arse. A 12 hour trip in total took like 20 hours…. Horrible. 1st Lufthansa flight - and will try not to book them again

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

We ordered kids meals - which were not kid friendly at all! (the breakfast that is - scrambled eggs on a bed of spinach and asparagus?)

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later
