Everything went fine on my Ryanair flight SKG-ATH. I checked in the day before and was allocated a window seat (19F).

Priority boarding was a joke - all it meant was you got on the bus first (and therefore off the bus and onto the plane last). I really wasn't bothered about this - I only purchased "priority" to get the extra hand luggage allowance.

Hand luggage was not being policed in any way. My bags measured more or less exactly the permitted dimensions and I noticed many people boarding with larger ones. Again not an issue, as it all somehow managed to fit into the overheads.

The flight was on time taking off and landed early. It was a pretty efficient operation overall and the experience was really no different from flying with any other airline within Europe.

Would I fly Ryanair again? The only thing I would worry about is irrops handling (or lack of it). But on a short route like SKG-ATH with plenty of alternatives, yes I would.
