Europe Packing List
The packing list I wish someone had handed me before my first Munich trip
I overpacked for Europe exactly once, on a consulting gig that took me through Munich, then Zurich, then a regional flight to somewhere I've genuinely forgotten. Four blazers. A pair of dress shoes I wore once. By the time I hit the second airport my shoulder was done negotiating with me. I checked a bag out of spite, and of course it came out on the belt with a bent corner. Never again.
Europe is not one climate or one carrier, and that's the actual problem with most packing lists you'll find. They assume you're going to Rome in July. You might be going to Rome in July and then Edinburgh three days later, in the rain, with a gate change at Schiphol in between. After doing this myself, here's the stuff I actually picked up on.
Carry-on size is not a suggestion, it's a fight you'll lose at the gate
I got dinged ~$50 at a European regional counter for a bag that fit every US domestic sizer I own. Expect a limit of about 22 x 14 x 9 inches from Verizon, AT&T, and T-Mobile. A lot of European budget carriers, Ryanair, Wizz — are stricter, sometimes meaningfully smaller, and they gate-check for real, with a metal sizer and zero sympathy. If your bag measures out around 22 x 14.5 x 10, it'll pass in Chicago and get flagged in Bergamo. I've had exactly this happen with a case that looked identical to my old one and was a half-inch too deep. Measure the bag you actually have, not what's printed on the box.

Layers over volume, always
I pack for a 9-day Europe trip in a 40L bag now, and the trick isn't magic, it's temperature math. One merino base layer, one packable shell, and shoes you can walk twelve miles in without regret — that's basically the whole list. Everything else is a variation. My wife still packs a "just in case" cardigan for every trip regardless of forecast, and she's not wrong often enough for me to argue anymore.
Zippers are the part nobody budgets for
This is the one durability lesson that cost me real money. I ran a mid-tier front-pocket carry-on, a Level8 Grace, actually — for about eight months of biweekly consulting flights, and the zipper pull sheared clean off somewhere around trip forty. Not the zipper itself, just the little tab you grip. I ended up working the slider with a keyring for two weeks until I replaced the bag. That matches what other owners of the same case have reported: it's a recurring complaint, usually landing around the three-month mark, and it's common enough on that specific line that I'd budget for a possible early swap rather than assume you got a bad unit. Someone said they had to rub soap on the zipper track before it would even budge, with the cubes already packed inside. That's not a fix, that's a workaround.
The front laptop pocket thing is real, and it's the reason I stopped checking a separate bag
Having a front pocket cushioned enough for a bulky laptop and a separate slot for headphones and cables completely changed how I move through security. TSA PreCheck lanes at DFW and Denver still want the laptop out, but a dedicated slot means I can grab it without unpacking every shirt I folded. That one feature alone is worth prioritizing over "looks premium in the store" — nobody at gate C22 cares what your bag looks like, they care that you're not holding up the line.

Wheels lie to you in showrooms
Showroom floors are carpeted or polished concrete. Cobblestones in Prague are neither. I've had spinner wheels that were dead silent in Best Buy and audibly rattling across smooth airport tile within a month, one owner review I read described the same noise complaint, wheels loud enough that people turned to look, on a case advertised as a silent double-spinner. Test wheels on the ugliest floor in the store, not the nicest one.

Checked bags for Europe: my honest take
If you're checking a hard-side trunk for a longer trip, don't assume "hard-side" means indestructible. I've read enough owner complaints about cheap checked trunks arriving dented on the first flight, one person watched a stranger's identical bag split open on the same conveyor belt, to know that shell material varies wildly by price tier. Spend the extra and check reviews specifically for durability complaints before you commit, especially on anything under about $140.
A packing list is really just a durability list in disguise. Pack fewer things, but pack things that survive the trip you're actually taking, not the one on the brochure.
