Good to know
- Set a price alert and book a few weeks in advance — fares on this busy route move quickly, and early booking helps you catch the better deals.
- Compare all three carriers (British Airways, Turkish Airlines, Pegasus): a full-service ticket may already include checked bags, while a low-cost fare can be cheaper if you travel light.
- The flight is only about 4 hours, so a carry-on is often enough — check each airline's baggage rules before paying for extras.
