Ryanair...hum...we recently had the RyanAir Experience when we flew home to Leeds from Gdansk. I was expecting the worst due to all I'd heard, but the flight wasn't that bad except DH being sat next to an extremely neurotic guy.
They are one of those who have all kinds of extra fees added on to their 'low price' quote - it never ends up being the price you end up paying. And you do have to pay for each checked bag - you don't get a free checked bag (much like other 'low cost' airlines I think) like you do with the major international long-haul carriers.
I can't see flying them long-haul to be perfectly honest, but it was okay for a regional European flight sort of on the cheap. *Might* be okay on a short-ish flight to the US - like maybe 5 hours +- to NYC & where you don't care to take much luggage (obviously).
And for people who've not flown Ryanair before, the one carryon bag is strictly ONE carryon bag with them - you don't also get to carry on a personal item (handbag, small backpack, laptop case, camera case, tote bag, etc) as well, like you would with *most* other airlines. And they really enforce this too. So your personal item has to fit inside your carryon bag (or be your sole carryon bag) - so if you're packing much, you *will* pay for a checked bag. Hubs & I each had our carryon (to the specified size & weight) for our trip back from Gdansk recently, and only needed to check one bag between us -- but we weren't bringing back any major shopping or stuff (like we would from the US). We had been on an extended trip so we weren't able to only limit to the carryon each. It made me a bit sad, however, as I knew I couldn't do much/any holiday 'stuff to bring back' shopping (Goldwasser...mmmm) as we had no space (or weight allowance) left to bring anything back.
That 'priority boarding' is a bit of a crapshoot on some flights - we had heard this before. If a majority of the people on a particular flight elect to pay for 'priority boarding' - then there really isn't any priority boarding if you're
all getting in the 'priority boarding' line so that could end up being a waste of money. I think you need to consider the destination & typical profile of who might be going there to gauge if you would actually end up benefiting from it. On our flight, we didn't go for it & neither did the majority of others who flew on that one - so might have been a benefit there.
We did pay to reserve specific seats - husband was reluctant to do this because we once did on Jet2 & didn't end up getting any of the seats we had reserved going or coming home. I complained to Jet2 about it - they referred me to their fine print T&C where it says even if you pay to reserve a seat, it's not guaranteed, so essentially they could just be taking extra money off you for nothing at all. We wondered if it would be like that too with Ryanair - but in fact, they were great about honouring the 'paid' reserved seats, even automatically herding people out of those seats who had not reserved them - so we were happy about that as we got into our assigned seats without hassle.
If you don't reserve a seat, then it's Cattle Call Airlines (moo moo moo) - much like Southwest Airlines in the US...everyone running & jostling about & cutting in the queue to get to the airplane first for better pick of 'find a seat & sit down!'. I don't see how hard can it freaking be to assign seats to everyone (on the boarding pass) - like most other airlines do as a matter of course, but sure that would 'rob' Ryanair of the opportunity to squeeze more money out of you for the flight.
That's my book & I'm sticking to it!
