I recall travelling to a Spanish island some years ago in early winter. The flight couldn't get in due to weather and approach aid limits (cloudbase was below the VOR approach limit), so we diverted to another island where the weather was OK.
Taxi to an hotel, rooms were all ready for us. Next day another taxi took us back to the airport where we were put onboard an onward flight to our original destination. Every aspect of the diversion and nightstop was paid for by the airline and it didn't cost any of us a penny. Or rather a peseta.
But that was before the bottom-feeding 'low cost airlines' dumbed down airline travel to its current nadir. How can you expect a proper service if you don't fly with a proper airline?
