I fly to Dublin and AMS for work. My flight are always booked within a few days of travel.
I've no real complaint about Flybe prices. Off to Dub on Monday, but as usual coming back via MAN and the train as I prefer not to wait for the morning flight back. The Flybe flight was cheaper than the Ryan Air back to Man (not my favourite airline - but the evening Aer Lingus meant that I missed the last direct train).
Oh on KLM. I've looked at this from Humberside a few times to avoid an overnight stay in the Netherlands. The roundtrip usually shows something insane like £450.
