We have Global Entry / Trusted Traveler. I need to see the expiration, so we can renew in a timely manner. They either expire next year, or in 2027. I forget, but need to verify.

My primary bag is from Rick Steves. When I bought it, it was expandable soft-sided. Fully zipped, it conformed to the European carry-on standard. Fully expanded, it conformed to the US (and international flight) standard. I'll need to verify if that's still the case (it may not be now). It also has rollerblade wheels. I hate spinners. They're great in airports, but total rubbish on cobblestone streets (which a lot of places in Europe have). The rollerblade wheels are effortless on cobblestones.

We also acquired two medium check-in bags. Alas, spinners. There's no point getting the big ones because the medium ones will fit 50 lbs easily. A bigger bag just means it's not as tight, and stuff can flop around inside.

I'll check out your bag suggestion. We've had Samsonite in the past, and they always seem to have issues. They can't seem to complete a journey without something breaking (handle tearing off, zipper pull missing, etc). My Rick Steves bag, and the two medium bags we got (Beis and Mono), appear to be quite durable. No issues to date.

We'll also have to review our lithium devices. If we need to know the ratings of our powerbanks, I'm going to have to take some notes (maybe write it on the powerbank with a sharpie). I already carry all such things with any meds in my personal item (usually my camera bag, if I bring it).
