The seat when "flat" was not flat and pad was too thin to cover it.

Awful customer service, horrible experience. We travel a lot domestic & international- worst flights to/from ever. Brief bkgd as Inhate to relive this experience: booked and chose 2 seats 4 months prior in Premium Economy - last row end seats close to bathroom, no one behind us, plenty of legroom;, underwear storage — flown this was on other airlines, love it. We receive notice 4 days before scheduled overseas flight - plane has changed, new seats assigned. Seats are split into single seats, opposites of the plane, FRONT Row so no reachable storage. Called BOTH British Air & America. American “switched planes and the seats you want are taken;” British Air “Yes, we’ll be glad to accommodate you (type type type). Just ask at the Gate and someone will give you new boarding passes with seats together in middle, OK?” — OK. —At Gate the attendant looks us up saying “No, it is an overbooked flight and yours are the only seats available.” But but but wait, “We were TOLD our seats had been switched and seated together?” Gate attendant “Well they were wrong and don’t change your seats. Your original seats are where you’ll sit.”. Right. No help WHATSOEVER. We sit opposite on way there, wife VERY disgruntled, a Tol 5 worst ways to start a 3-week bus tour of UK. We promise to NEVER FLY AMERICAN OR BROTISH AIR EVER, and we have 3 more extensive trips planned..

They lost my bag. ... And I asked them 3 times to 3 different people if my checked bag will maKe it all the way - they all confirmed and at the end it was left at the connection... Bravo

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

British Airways is an excellent airline. Comfort, food and airline personnel.

Older airplane with worn out seats. No entertainment system at all. Connecting to Wi-Fi was problematic and hit and miss.

An delay of almost 3 hours while passengers were already in the plane kept us very uncomfortable. The food was also very limited. A bad experience overall.

I understand that there is a catering issue - water should be the minimum stock. During the flight, not once that the attendants came through with water. The conversations in the kitchen were very loud and they were swearing. I do not expect any white glove service, at the minimum, we should be cordial. It was almost an inconveniece that we were on the flight. And it made us feel if you even dare question us, we'll make you deplane.

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

Long line with check in at the DIA British Airway counter.

The flights were on time. Cabin crew were nice. The food was terrible! Checking in was not easy using my phone.

Crew were fantastic and the aircraft was extremely comfortable, but outdated. Headphone jacks were worn out and sound normally only came out of one ear unless positioned just right.

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal
