Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

I love American. I’ll never fly anyone else if I can help it.

Boarding was organized and timely. Food was mediocre, especially for first class travel.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Nice comfortable flight from Barcelona back to the states. The premium economy offers the extra room we need for my husband. The food was good and our flight attendants were excellent.

in chicago, you have to go out to drop off your luggage for a connecting flight and come back into a security check. which was horrible with a government shut down. some airports you down off luggage and go to your gate. things were not cleanly marked.

Premium economy seat was decent. As always poor headphones, poor food and beverage, crew is not overly friendly

I couldn't use their app to select seats or check in because they made a business partnership with UnderPricer to control and sell those options when you purchase your tickets through that agency. And yiu can't get any assistance from UnderPricer. Vueling has made a terrible business decision to partner with them.

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional

30 minutes still don't have gate number, ask many people can't get answer.

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

The crew was super friendly and helpful. The food was quite good. An overall positive experience.

the seats were bad and uncomfortable and the food was not tasty.

The crew was amazing. I appreciate the level of professionalism in the Iberia crew.

A more organized boarding experience and better food would have made the experience better.

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.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

why can't planes be boarded from back to front?? everything was great otherwise

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Awful. Flight was late. Follow flights cancelled. No person at the British airways counter for hotel voucher. Awful service.

Well unfortunately our connecting was cancelled and next flight delayed. Was in airport 9 hours. Flight itself was good. I’m sure it was a FAA problem.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

horrible! after going through hell and back to get a flight home after my flights got cancelled I also had a delay of 2hrs stuck inside the plane because of some technological problem.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

I thought we were screwed having to pay an additional $300 to pick our seats. My wife and I think it’s important to sit together on long flights and British Airlines use’s that against us charging over $300 on top of an already high fares. In the future, I’ll try to avoid using British Airlines, and KAYAK and stick to American or United.

Yet again BA flight was delayed. Only one delayed. No updates from ground staff. Plane was dirty and staff were disinterested.

BA gave away one of the seats I paid for. Within the last minutes before boarding, my partner couldn't make the flight. I should have had a seat next to me that was empty.
