I seem to remember that an Electron card ... is the sort of card you get if your bank determines you're a sufficient credit risk that they don't even want you to have a cheque guarantee card or a facility for transactions that are not cleared directly from your account.
Perhaps this is RyanAir catering to their demographic

I'd like to think LiarAir were this smart, but I'm sure they just want to milk the maximum revenue from their customers and blame everybody else for the cost of the extras.
Funny thing is we used LiarAir last week. Given their poor reputation for timekeeping and customer 'service', I paid by AmEx to make sure we had insurance coverage. This cost £4 on top of the £0.01 and taxes. Oddly, the flight arrived on time in both directions, and apart from the inept bag handlers at STN, we had no problem.
I think I'm right in saying that easyJet charge £3 for Visa/MC and £5 for AX, so differential pricing is possible. Of course, as a real airline, EZ make no charge for debit card use.
