Pegasus Airlines offers passengers the option to select their seats in advance, which can usually enhance the travel experience by ensuring that travelers sit in their preferred seats. This service typically applies to both standard and extra legroom seats, depending on availability. Passengers can choose their seats during the booking process or later by managing their bookings through the Pegasus Airlines website. It is important to note that there may be an additional fee for advance seat selection, especially for certain seat types or locations within the aircraft. If a passenger does not select a seat in advance, they will usually be assigned a seat automatically at check-in. For the most accurate and up-to-date information regarding seat selection options and any associated fees, it is advisable to refer to the official Pegasus Airlines website or check the details during the booking process.
