I wonder how many of those politicians did use this offer and whether it was obligatory for them?
The EU discriminates against Ryanair and I think with loco's in general believe it or not, well at least that was the case in 2011.
Michael O'Leary gave a speech at the Innovation Convention in Brussels that year and was invited to the event with the EU offering to pay for his flight to/from Brussels
Zaventem and with a driver awaiting his arrival - However MOL requested the driver pick him up at Charleroi on a flight from Dublin. He even offered to pay for it himself, they refused wanting him to fly to Zaventem. MOL arrived via taxi flying to Charleroi. Kind of sums up politics in general though?
Being honest I don't think there were a great deal of European ministers using those Ryanair flights especially not Barroso and Co., Irish TD's probably did though as well as Irish MEP's.
