Whether you need to collect your bags during a layover in 2026 depends primarily on your destination and the "port of entry" rules. For domestic-to-domestic flights (e.g., New York to LA via Chicago) on a single ticket, your bags are almost always checked through to your final destination, and you do not need to grab them. However, for international-to-domestic arrivals (e.g., London to Dallas via New York), you must collect your luggage after clearing immigration, walk it through customs, and then drop it at a "re-check" counter before heading to your connecting gate. This "first port of entry" rule remains a standard in 2026 for the US, Canada, and India. Conversely, many European hubs (like Frankfurt or Amsterdam) allow baggage to be "through-checked" for international connections without a mid-trip pickup. If you have booked two separate tickets (a "self-transfer"), you will always need to collect your bags and check them in again for the second leg of your 2026 journey.
