Whether you need to self-transfer your luggage depends on if your journey is booked on a single ticket or separate tickets. If you booked a single itinerary with a full-service airline (e.g., Delta or Emirates), your bags are usually "checked through" to your final destination, and you do not need to collect them during your layover. The exception is when entering certain countries like the United States, where you must collect your bags to clear customs at your first point of entry before re-depositing them on a transfer belt. However, if you "self-connect" by booking two separate flights (common with low-cost carriers like Ryanair or IndiGo), you must collect your luggage at the transit airport, exit the secure area, and check them in again for your second flight. In 2026, many travel sites offer "Self-Transfer" protection, but this doesn't change the physical requirement of re-checking bags. Always check your baggage tags at the initial check-in; if the tag shows only the intermediate airport code, you are responsible for the transfer.
