Sure some of this has been covered before although it didn't come up in a quick search. I am pretty loyal to BA but when I do stray, it becomes very apparent there are a few areas BA could really improve by just looking at what their competitors / alliance partners are doing:

- boarding - having a procedure that is stuck to and that doesn't end up in the whole plane descending on one agent at the same time
- baggage transfer - unreliable at Heathrow in a way that it isn't at US airports
- starters - in Y, starters tend to be carb mess with mayonnaise. in C the salads come with some dressing that surely most people don't like: chilli lemon? If something decent can't be afforded, don't do one.
- collecting rubbish in the cabin as they go along - a BA plane looks much messier than their competitors by the end of the flight because the crew very rarely collect rubbish
- cleanliness of the flight on boarding - BA has to be one of the worst of its main competitors at this.
- assistance in transfer at Heathrow - why do other airlines announce gates and BA never does? Sometimes competitors meet people with tight connections too....

I like BA and will stick to them. I like the tea, the chat from the captain, the fact that they seem to try to fly around turbulence rather than straight through it, the London Pride... I could go on. But put some effort into sorting these things out BA please....
