Bit short I know, but I've been in travel for 20 years... and have a bit of a nose for these things
I've got 100 or so travel domains, mostly capital cities and airlines - some typos, they only get a few clicks a week and at $0.10 a click they only just cover the reg fee.
I thought acheapflight.co.uk was a cracker - but it ain't
Good luck, but not worth the reg fee IMO
