I can understand why you worry about the spacebags -- they really do make a miraculous job of shrinking down to size something that would in no way fit in the suitcase along with the other packed items.
But I would hope that, having seen more and more spacebags starting to come through, the staff at airports might even now have a vacuum handy to "re-suck" a spacebag if they've felt the need to open and search it, hopefully.
I brought my down feather full-size comforter quilt, two bed pillows, and two decorative pillows, in a suitcase, also packed with other belongings, all thanks to the miracle of some spacebags, lol. Talk about Mary Poppin's bag with all the items inside. Mercifully nobody seemed to have opened or searched the bag or tried to release the spacebags -- that stuff would never have repacked without the spacebags.
I thought fleetingly about the potential problems if those things had to be deflated/reflated again, but llike I say, hopefully that won't even happen, or if it does they've got to have a vacuum handy I would think. Spacebags must be so frequently seen now.
