I actually dealt with Turkish Airlines baggage allowance a few months ago when I was flying from New York to Istanbul, so I can share what I learned from the experience. At first, I was a little confused because the rules depend on whether you’re traveling under the piece concept (used on U.S. routes) or the weight concept (common in many other regions). For my U.S. flight, I was allowed two checked bags up to 23 kg each in economy, which was more than enough for my long trip.
The tricky part was that I had also booked a connecting flight within Europe on the same ticket, and that leg followed the weight concept—so I almost got caught off guard. Luckily, I double-checked the policy before packing. Turkish Airlines’ site explains it, but honestly, I found it much easier to just call (877)-764-3622. The agent quickly walked me through what applied to my route, helped confirm my booking details, and even reassured me about my carry-on size.
If you’re planning to travel, I’d recommend giving them a quick call. It saves you from last-minute airport stress and also makes booking, canceling, or modifying flights a lot smoother.
