This was us our trip a couple weeks ago.... while flying on the plane it occured to me, AHHH, forgot to put the yellow tags on the luggage! 9th trip, always do it... not sure why I forgot!
Thankfully, only had one checked piece. But was fuming, thinking it would slow us down and we'd have to wait longer for a bus. Turned out perfect timing, luggage came right out, and made it right onto a bus full of people that had been sitting a while waiting to fill up.
Carry ons though... four of us, each with four carry ons - whatever dimension that airline we're on allows, we make sure to have it as big as we can. Just like having everything with us and not checked (and also the cost issue of checking luggage)
But am SOOO glad I remember in air I left the yellow tag off - would have gone to resort and wondered why our luggage never arrived if hadn't realized it!
