Not sure how much more convenient this would be compared to other destinations, but the info is there if you need it.
I was quite shocked when I heard that Kidlington airfield is no w accepting international flight, you can get there from Geneva, but only one a week...
I love Baboo and am so happy they are flying into London City now.
We flew Baboo to Athens over the summer and the whole experience was great. Assigned seating, no nitpicky luggage rules, free snacks and drinks (including wine) on the flight and all for the same budget fares as the Easyjet/Ryanair crowd.
Seriously, if you have the choice, go with Baboo everytime over the budget alternatives.
