I have a question. I looked on the Ryanair website but couldn't find anything.
My last flight with them was 3-4 years ago. Back then we traveled around England on Interrail and then flew home from London. I had to check my trekking backpack in with the bulky luggage. I don't want to end up at the airport and have them tell me they didn't mention it when booking and now they have to pay xy€. If you have a stroller you have to mention it when booking, does anyone know what the situation is with large backpacks? I just declared 1 piece of luggage when booking.
