Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

I like everything about British Airways. Excellence. Perfect. Exquisite service.

Awful it always is unfortunately is the only way to fly direct to london

Ohooo it's fantastic 👏 I love it 😀 😍 ❤️ it's on time ⏲️

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

Need to offer Better food from LAX to London Service from London to Delhi very delayed after take off.

Great crew and food and beverage. Seating tight but not the airline's fault. Will definitely fly BA in future!

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?
