My experience with British Airways is excellent, thanks for all 🫶🏻✈️

Our luggage arrived 2 days late when we reached Santorini. We were without cloths and toiletries for two days and didn't had time or means to go and shop everything at reasonable cost. Even though, we filed the report immediately at the airport, there was very less communication to us about when we would expected our luggage and even when it arrived there, they didn't had staff to deliver luggage to our hotel, so we had to go to airport to pick it up, which is very difficult and annoying to do in foreign country where you don't have you own vehicle and you don't have time because your tour is packed with activities. They could have tried to expedite the process and kept us informed and deliver the luggage at our hotel. Also, should have given us compensation for it.

Fair, difficult to find the departure gate. Luggage delayed on arrival

Very old aircraft. Seat 15 A & B personal light not working, foot rest broken in 15 A , reclining push buttons required two people to do it. Overall experience was below standard. The same food was served both the times. No snacks in the ally, drink choices very limited. It felt like it was the year 2000. The crew unfriendly, hospitality 4/10.

Friendly on board crew, kept informed on flight. Pre-ordered food arrived as ordered

The crew is very friendly and helpful. The food is good for airplane food. The flight is long and hard to sleep. The leg space is great. The plane arrived in plenty of time.

I would like to recognize a crewmember for her above and beyond service. Her name is Emily Milburn. The flight was delayed for more than a couple of hours, as we sat on the tarmac because of a storm in London. I could not connect to the Wi-Fi, which I needed to do to arrange for my follow up flight back to the US. This young lady told me that her cell phone had reception and offered to provide me connection through her phone. I was beyond impressed. Later on the gentleman sitting next to me, could not connect to the charging portal. Emily came back with her personal auxiliary battery and offered to the other passenger. She certainly needs to be recognized by British Airways for going above and beyond what is expected. She was the ultimate professional and very friendly, and I have to admit that, given the delay, the passengers were not the easiest to deal with.

Both the flight from/to San Diego and London went very well. There were lots of movies from which to choose for entertainment, the food was nice, and the flight departure and landing times were good to minimize jet lag.

They damaged my check in bag and when I filled complaint they gave some minimal amount which is not even sufficient to buy new bag. Vey unhappy with this experience.

Bag drop in Jersey was very long. British Airways could have had more people available to check bags.
