Since nobody here seems to have a clue, let's if Ryanair CEO Michael O'Leary has any ideas:
Turns he does! And it's a pretty good one, to boot. During a German press conference to discuss the possibility of a new transatlantic airline, O'Leary told reporters that under his management there'll be blowjobs in economy and business class, for-pay and for free, respectively.
Obviously this a product others airlines would be wise to emulate. At the very least we'd see a reversal in the rapid declines in business class travel, a reduction due in large part to the financial services slow down. In-flight fellatio? People will find a way to get deals done.
