A few things to share about my recent trip.
This applies to Ryanair, Wizz Air, and really any airline where the free on‑board baggage allowance is 40×30×20 cm or even smaller. I travelled with the WINGS COMPRESA backpack — the one with the built‑in vacuum compartment. The manufacturer claims it’s perfect for airlines with a 40×30×20 cm free personal item allowance… but honestly, that feels more like a marketing trick than reality. Even when I packed the bare minimum — a pair of trousers, a hoodie, and my laptop — the backpack already exceeded the allowed dimensions. The laptop compartment and the padded back alone add around 6 cm, and the number of internal pockets eats up a lot of usable space. With personal‑item luggage, every single centimetre matters, and this backpack wastes too many of them. That’s why I started thinking about how to avoid this problem on my next trip. With this backpack, if security had checked me at the gate, I would’ve been charged €75 for not fitting into the sizer. I avoided the fee only because no one checked me — pure luck. So before my next flight, I sat down and asked myself how to prevent this from happening again. The solution came quickly: get a suitcase that fits the dimensions perfectly. I ended up choosing the WITTCHEN ABS cabin suitcase with detachable wheels. It’s exactly 40×30×20 cm, and the wheels come off in seconds. And here’s the best part: on my next trip, I was checked both on departure and on return. In both cases, I simply detached the wheels in front of the staff member measuring the luggage, placed the suitcase in the sizer, and it fit without any issue whatsoever. I’m considering adding individual luggage ratings in the future, so you can know what truly passes airline rules — not just what the marketing says.
