No, it's not a mistake. WOW Air, the Icelandic low-cost operator, announced the first aircraft Airbus A330-300 will wear the sign TF-GAY, a name chosen to support the LGBT community and their rights. WOW AIR CEO Skúli Mogensen says TF-GAY's appointment to support the LGBT community is in line with the company's values.
From the very beginning, WOW AIR started playing with these aircraft registration codes. Currently, the 6 aircraft existing in the WOW AIR fleet have the following indications: TF-MOM (A321), TF-DAD (A321), TF-SIS (A320), TF-BRO (A320), TF-SON (A321) and TF-KID (A321). Follow TF-GAY to the first A330-300, which will arrive in March. The other 2 Airbus A330-300 will be received in June and will carry the TF-LUV and TF-WOW codes. As you can see, the values of WOW AIR are family related and support equal rights for all, regardless of gender, religion, ethnicity or culture.
Going back to the 3 Airbus A330-300, they will be able to carry up to 340 passengers in one class and will operate flights on Reykjavik Keflavik - Los Angeles (15 June 2016) and Reykjavik Keflavik - San Francisco (9 June 2016) routes.
