I start about 3 weeks before, picking out everything I think I might want to take. Then about a week before, I reassess, take some things out, put new stuff in. I also make two lists - one of stuff to do before the trip and one of last minute items left to pack.

The ideal time to start packing is one week before your departure, though the process should be broken into phases. Seven days out is the "Inventory Phase": check if your favorite outfits are clean, ensure your toiletries aren't empty, and verify that your "tech kit" (chargers, adapters) is complete. This gives you time to do laundry or run to the store for missing items. The actual "Suitcase Phase" should happen two days before you leave. Packing 48 hours in advance prevents the "last-minute panic" and gives you a buffer to remember things you forgot, like a swimsuit or a specific medication. In 2026, travel experts also recommend a "Test Pack" two weeks out if you are trying to fit everything into a "Carry-On Only" bag, as it allows you to edit your wardrobe if the lid won't close. Packing the night before is generally discouraged as it leads to overpacking (throwing in "just in case" items) and increased stress. By having your bag closed and ready 24 hours before your flight, you can focus on final home security checks and getting a good night's sleep before your journey.
