Turkish Airlines offers several opportunities to upgrade to the Business class or First class cabin. While some of these options are accessible to all travellers, some are only available to those with elite rank. There must be space for you to upgrade and you must have a ticket that qualifies for one. Unless the airline confirms it, an upgrade on Turkish Airlines is never guaranteed. <a target='_blank' rel='nofollow' href='https://www.travomojo.com/upgrade-class/turkish-airlines-upgrade'>https://www.travomojo.com/upgrade-class/turkish-airlines-upgrade</a>/
