I seriously doubt that anyone that can afford to buy Haganai luggage would A) be traveling and B) actually use it. People that buy this are more likely to put other Haganai merchandise inside of it than actually take it out in public. If you did take it to the airport I can guarantee your bag is getting checked by security. They're only $300 bucks or so each. Also is there some reason the youngest character on the show needed to be flashing her underwear? Gross. Source
