Geez Zarg, I know the road to WOL and the airport pretty well and I can guarantee that I'd leave more than 1:20 to get from WOL to check in. In fact, I'd leave about 1:20 to get to the airport and then 20 to get from the car park to check in- especially if I knew in advance about the 30 minute check in policy!
Considering that they did you the favour (according to their rules), why wouldn't you fly them again?
