On the occasion of its 70th anniversary, Tunisair unveiled 737 TS-IOP "El Jem" in a 1950s retro scheme. The livery itself is a red variation of the Air France scheme of the times. The aircraft was unveiled in Tunis on December 11, 2018.
Tunisair again added decals for its 70th anniversary, with the above three aircraft receiving large "70" stickers aft of the wing while the rest of the fleet only got smaller decals (located in various positions). A retro livery was unveiled on 736 TS-IOP on the occasion.
