strange, normally other way around!!
depends on who you apply for, all i know from flying with Britannia is there were 3 or 4 people on my course who were 45+.
i lived with a guy who was ex RAF of 20 years as a caterer, he was 45 or so if i remember rightly.
don't know about anyone else, but press recently saying getting rid of crew that are too old at B.A. at mo so that is probably no go.
i am in same boat at mo, trying to get into Emirates, but fear am too old, and married for them.
Hope this helps
