All I know I just booked my Christmas holiday with them for £ 19.99.
BA were asking me £ 200 for the same route. (Only they don't fly it on the day I wanted it)
KLM about £ 1200 (sic).
I'll gladly splash out £ 2.50 for an overpriced cappuccino on board !!
(Oh, and it's to the same airport, not somewhere 100 km away !)
