Airline reviews

British Airways provided prompt service and maintained excellent cleanliness throughout the flight. However, the business class seats felt tight, and the cabin temperature was uncomfortably warm, making it difficult to sleep. Since I couldn’t rest, I turned to the in-flight entertainment, but the selection was heavily focused on Paramount content, which isn’t my preference. I also found the Bollywood movie options quite limited compared to other airlines. On the positive side, the spirits selection was impressive, and the staff was exceptionally friendly and attentive.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

It was just ok. Half the bathrooms were broke on the flight.

Aer Lingus was the actual airline so they handled everything professionally.

Didn’t make flight and then forced on connecting flights back to LA that cost me another day of travel on an inferior experience.

No land services during boarding, specially while moving from terminal to another

Need a do not disturb sign if you wish not to have any meals so that they can wake you or have the meals served . Left very sad and hungry .

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

I am 70 with carry on bag. Was told to go down two flights of stairs the had to climb stairs at rear of plane. Skywalk to front of plane was not offered. I was in row 26

It was a one stop flight. What I didn’t realize is that when we landed at London’s Gatwick it was necessary to go through immigration/customs and then go to the departure desk to get a new boarding pass…then pass through security again. There was only a 1 hr/20 min layover which is not nearly enough time to do all that. There were at least 12 people on my flight from Dubrovnik and 7 of them missed the flight to JFK. It was horrendous and British Airways should never have considered it a reasonable thing to do. I, literally, ran the very, very long hallways, up and down escalators and stairs…ran on the moving sidewalks and arrived quite wet from perspiration in time to board. Be sure to give yourself at least 3 hours to make any of those connections at Gatwick.
