On time. Comfortable sats. Clean aircraft. Friendly crew. Good food.

The British airways from Dallas to London is not great , the food is not good at all but BA from London to Delhi is amazing food is great.

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

I Keep your expectations to low to middling with BA, or most European/ US airlines these days.

British Airways offers amenities subpar with all other airlines flying internationally. Sharing tis based on my experience with flying at least five other airline between IAD-DEL in the last six months.

Experience was bad. In business class, they ran out of food choices. Luggage was delayed by 2 days in both to and fro flights, ground staff was not helpful, took 3 hours to log the complaint for missing luggage.

Very bad because flight was cancelled and they never informed me i have to wait for three days in hotel to get another flight

Missed food service or not enough food available to serve the passengers. Very poor leg room in economy. Uncomfortable and old seats with some of the seat covers coming off. Lights, entertainment system and call buttons not working for an entire section of the flight between Del-Lhr. Very poor experience overall.

They ran out of earphones so my 3rd daughter couldn’t use the on board entertainment the entire flight. They also ran out of food choices (chicken or cheese) by the time they got to the last few rows, so my oldest daughter, wasn’t given a choice. Luckily she isn’t a vegetarian because they only had chicken left.

Biz class has a middle seat. 🙄. WiFi only for first class. No free seat assignments. Basically nickel and dime approach. They need to take lessons from Singapore Air and the likes. Never again.
