I think it’s helpful to look to Ryanair to see what new fees those of us in the US can look forward to in the next year: The low cost leader previously had allowed those who had checked in online to go through priority boarding for free. The result? The priority boarding line was often longer than the non-priority boarding line. So they’ve come up with a better solution: It’ll now cost you GBP4 (or 5 Euro, about $8) to get priority boarding. Online check in is still free (for now).
