suitcase, not expanded. I pack my purse into the other bags, lienavg relevant things (wallet) easily accessible. On the way back, if you need more room, expand the suitcase and carry the purse. If it fits in the overheads, you're fine. The worst they'll do is gate-check it.You get your shoes, you get your time with the #scio10 crowd (when you said peeps, I thought you meant peep-toes for a second). Perfect!
