I'm about to book some trips away for later in the year. Ryanair and easyJet prices are similar and my preference is to fly Ryanair. I'll be booking easyJet, though, and for one reason only: I'll be away for more than a fortnight so would not be able to check in online for both flights before leaving home if I choose Ryanair.
Come on, Ryanair. Why can't passengers check in online earlier?
