Air Herler is an airline featured in Grand Theft Auto V. It doesn't have any known destination, but the English name and the logo, which seems to be a piece of the Union Jack, suggests it most likely is a British company. The livery of Air Herler's planes is also similar to that of British Airways.
It is frequently found in Los Santos International Airport and has a fleet similar to that of FlyUS, consisting of Shamals, A320-like uncontrollable airliners and Jets. The wreck of an Air Herler airplane can also be found in the Grand Senora Desert bearing a different livery, therefore most likely being an older version.
In the online mission Landing Strip, players have to hijack an Air Herler Shamal that is known to be carrying drugs. This might imply the company is involved with illegal underworld businesses, yet chances are the aircraft is most likely stolen.
Its name is a reference to the word hurling, a slang term for vomiting, which is a common occurence on airplane flights.
