Opps, didn't realise that this would cause an issue. Lesson learnt. Apologies!
Not at all. My post was not meant in any way as a criticism of you - I think it's a kind thing to want to do, to write a letter of thanks to someone who has made you happy.
My comment was purely as I stated it - the airline industry has forced passenger expectations so low that service that would have been seen as standard 20 years ago is now apparently so unusual that it is worthy of praise.
