Flying Ryanair for the first time next month, and wondering how strict their luggage measuring is. None of our carry-on luggage fits their weird dimensions for the 10kg carry on (55cm x 40cm x 20 cm). It's the last measurement, the 20cm depth, that is screwing us over. Our carry-ons all are 9.5", which is ~24cm. Has anyone else had this problem?
Our carry-ons are these:

I've never seen Ryanair gate staff measure cabin luggage (assuming you've paid to take it into the cabin)
Hard to imagine 4cm would be obvious to the naked eye!

Agree with the previous poster. The gate staff is too busy looking for full-sized carryons among non-priority passengers (in order to charge them extra), they will unlikely care about 4 extra cm.

Since you are flying them for the first time, don't forget that with Ryanair, you have to pay extra ("priority and two bags") to take a full-sized carryon aboard, such as yours. Otherwise, you can only take a really small bag into the cabin (40x20x25cm, about 1/3 the size of a regular carryon).

Also, there's a fee for checking in at the airport, so don't forget to check in online.

Hi, what is a full size carry on? Compared to regular cabin luggage?

Those of us in the non priority queue are allowed smallish shoulder (non roller) weekend bags

Anybody in the non priority queue with a roller is singled out for payment extraction - low hanging fruit

Gate staff don't worry about the size of rollers in the priority queue (as long as reasonable), and they don't worry about the size of soft shoulder bags in the non priority queue (as long as reasonable)

Interesting, thanks for the info! Have you ever used a regular US sized carry-on on ryanair before?

Yes, I occasionally pay extra to take a wheely on board. Why do you ask?

I think the OP asks about first hand experience with the slightly larger US sized carry-on trolleys that are customary in the US but in principle are too big to be allowed as cabin baggage with many/most European carriers, including Ryanair.

No first hand experience, but after several Ryanair flights and experiencing how this is dealt with at the gate of Ryanair flights, there is a very good chance that the gate agents will not notice anything if you bring a trolley that is 24cm in depth rather than 20 cm. The difference is insignificant and hard to notice. However, you definitely will have to purchase the "priority & 2 cabin bags" option in order to successfully bring a carry-on trolley onboard (regardless if US sized or "European" sized). As mentioned above any pax with a trolley (but without having purchased the priority queue option/full carry-on allowance) will most likely be singled out and requested to pay for excess lugagge at the gate (then it is much cheaper to buy the "priority & 2 cabin bags" option in advance).

Anyone having problems logging into their Ryanair account? I've tried on three separate devices and it keeps telling me "no connection".

I had Ryanair tickets London Stansted - Alghero for early October which I decided not to go, I changed it for a flight which going to be canceled, paid a bit for Ryanair hidden extra for increased seat and lagage cost. Once the new flight was canceled I got a full refund, original price plus extras.

The question is: how do you know which flight going to be canceled by Ryanair? I placed my bet on London Stansted - Podgorica, as Montenegro is in the red zone for Uk, with little chance those flights would operate any time soon.

Those flights are still on sale for October so this gamble might still work for some. Even if you missed 7 days window or your flight is not eligible for a free change, once a new flight is canceled you got back the whole amount including any change fees you paid earlier.

A first time on Ryanair (DUB-EDI) and I am a convert...........
Priority boarding and 2-bag carry on seems to be the way to go. Out of EDi, Ryanair operates many non-stops, incl. to Faro.

There is a first time for evertything. I have travelled with FR for ears without major issues.

Yes, just add the "priority& 2 bags" when you make the reservation (it will be more expensive to add afterwards) and you will be fine.

Hello everyoneI have two FR booking in October. Yesterday I went to MMB to pre-order coffee and maybe some snacks, but the option was gone. Is that a glitch or recent "enhancement"?

I ordered the 10 EUR Lunch/Dinner deal 3 weeks ago (when I made the reservation; not subsequently).
