Are they meant to be so fecking difficult to get in? I have just struggled for twenty mins with mine and I can't work out for the life of me how it fits. I've taken off the wheels.. tried every which way. It is the correct size, silly shop sold me a bag for a Vibe last week as I discovered at the departures gate at Gatwick North Terminal (grrrrr) so I thought I'd try this replacement one before we fly next week... it's flipping impossible to get it in though and I'm starting to lose my rag!
