So your statement that "60 % of passengers don't pay cc fees" was inaccurate then, or rather at best it was out of date, so back to the point I was making, Ryanair made £400 Million last year from reselling CC charges without which their profitability as a business would have been zero. Electron hasn't been FOC for 12 months or so.
Note, before I am jumped on by yet another O'Leary worshipper, at no point have I actually criticised them for this, they make their money through somewhat sharp business practice that penalises the less savvy traveller. I don't have a huge problem with that as it allows those who do have some knowledge to access cheaper fares.
That said I really don't see why they can't simply absorb the CC fee and online check in fee into their base price, they'd still be the cheapest (in most cases) and customers wouldn't constantly feel like their being cheated.
