Typically in economy, you can bring one carry-on and one personal item. If you bring two bags, one must fit underneath your seat and the other can go into the overhead bin. If you're flying in an upgraded class like business or first, you may be allowed an additional carry-on bag.

Yes, you can carry two pieces of luggage on almost any flight in 2026, but the cost and "location" of those bags (carry-on vs. checked) depend heavily on your airline and ticket class. On full-service carriers like British Airways or United, an Economy ticket usually allows for one "personal item" (backpack) and one "carry-on bag" (roller) in the cabin, plus a checked bag allowance. However, in 2026, the "One Bag Rule" has become strictly enforced at many airports in India and for "Basic Economy" tickets on low-cost carriers like Ryanair or Spirit. On these flights, you are often limited to just one small bag that must fit under the seat; any second bag, even a small handbag or laptop case, must be paid for and checked in. For long-haul international travel, the "two-piece rule" is standard for checked luggage, allowing you to check two bags (usually up to 23kg each) for free in Premium Economy or Business class. Always check your specific 2026 "allowance" on your boarding pass, as "gate check" fees for an unauthorized second carry-on bag have risen to as much as $75–$100 on many major airlines.
