Yes, you can absolutely put your purse inside your backpack, and in 2026, this remains a top "pro-tip" for navigating strict airline baggage policies. Most airlines follow a "one carry-on and one personal item" rule. If you are carrying a roller bag, a backpack, and a purse, gate agents will likely ask you to consolidate them because they count as three separate items. By tucking your purse into your backpack, you reduce your count to two items, ensuring you aren't forced to pay gate-check fees. This is especially critical when flying on Basic Economy fares or budget carriers like Spirit or Ryanair, which may only allow a single personal item that must fit under the seat in front of you. Just ensure that the combined backpack is still within the airline's size dimensions (typically around 18 x 14 x 8 inches for personal items) so it doesn't get flagged for being overstuffed or too bulky to fit in the required space.
