Hand luggage only, for two nights
Skipping the hold removes queueing, waiting and the risk of losing the trip's clothes. Two nights makes it easy.

There is a short answer about packing for two nights and a useful one, and they are not the same. What follows is the useful one.
The short version
- Cabin bag dimensions vary by airline and are enforced at the gate.
- Two nights needs one change of clothes, not three.
- Liquids remain the main constraint where old rules still apply.
The time saved is substantial
No bag drop queue, no baggage reclaim and no risk of a delayed bag on a two-night trip where a lost bag is the whole trip. On a short break that can be an hour or more each way, which is a meaningful fraction of the time available. It also makes a same-day connection or a late change of plan far easier.
Two nights is genuinely small
One change of clothes, one spare layer and the toiletries you actually use covers it. The common failure is packing for imagined contingencies rather than for the forecast. Anything you can buy cheaply at the destination does not need carrying.
Check the dimensions, not the label
Cabin allowances differ substantially by airline and some carriers charge for anything above a small personal item. Gate sizers are enforced inconsistently but are enforced, and gate bag fees are punitive.
A soft-sided bag that compresses passes situations a rigid one does not.
Liquids where the rules persist
Where the older restriction still applies, containers must be within the limit and in a transparent bag. Solid alternatives — bar soap, solid shampoo, toothpaste tablets — remove the problem entirely. Rules now vary by airport during the scanner rollout, so pack to the strictest airport on your itinerary.
None of this is a substitute for talking to a clinician if something feels wrong.
Wear the bulky things
Coat, boots and any heavy layer travel on you rather than in the bag. This is unglamorous, entirely normal and frees a surprising amount of space. It also keeps you warm in an aircraft cabin, which is usually cold.
The takeaway
One change of clothes, wear the bulky things, and check the sizer dimensions for your airline.
Pick the one that costs you least, and let the rest wait.
Questions readers ask
What size bag should I buy?
Something that fits the smallest allowance among the airlines you use most. Soft-sided compresses into sizers; check specific dimensions rather than litres.
Can I take liquids through now?
It depends on the airport, as scanner upgrades proceed unevenly. Pack to the strictest airport on your route to be safe.
