First time flying them (TNG-MAD) - My backpack is slightly larger than the size on the web site they is the limit for a Backpack is this a situation where I need to put it in a sizer and I can smoosh it down to the correct size (its a backpack and smosshable) or are they going to measure it and be un cool about it. I have read and herd the horror stories of Ryan air so want to see if I need to use smaller Backpack or can use my traveling companion for many years not huge but 3-4 inches over length. not back to the brim so can be folded/smooshed to fit a bin sizer - Thanks!
