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

Every flight was delayed. They lost our luggage for days.

On time. Clean. Efficient. Just what is required for the short hop.

I love my flight from Munich to San Diego — highly recommend British Airways.

Very crowded, no real explanation of food "chicken or pasta?" After dinner no drinks service. Plane was clean, but little help with finding soaces fir luggage to get into overhead bins. Many passengers putting 2 bags, hats, duty free in overhead bins so no space for roll ons

The boarding was smooth, seats comfortable, crew friendly and helpful.

The crew were good. The flight was on time. The food was bad.

Only for BA because we had to get to Edinburgh at a certain time. Baggage lost, late boarding with only one person checking, again, our passports and boarding passes until the despatch controller had to step in to get us away. Will never fly BA again.

I always have issues to connect with BA WIFI. Nothing to blame BA for but there is always an issue getting a gate at any London Airport whether the flight is on time or delayed. But overall a great flight.

Bad. After 3 hours on tarmac, flight got cancelled. No assistance whatsoever from BA.
