Low-cost Austrian airline FlyNiki claims it is launching the shortest international flight in the world: a 30-mile trip between Vienna, Austria, and Bratislava, Slovakia, which would only take 10 minutes.

The flight is so short that it would be difficult for passengers to even take a power nap. So short, actually, that it might just be a stunt: The new service starts on April 1 — better known as April Fools' Day.

But if it's a joke, it's an elaborate one. FlyNiki is accepting reservations for the service on its booking website, for prices starting at $35 (29 euros) one way.

Stunt or not, there's more to question about this aerial jaunt.

Whether FlyNiki is correct in claiming the title for world's shortest international flight is up for debate, according to The Telegraph. That distinction may belong to Cameroon's airline Camair-Co, which flies the 20-mile distance between Kinshasa, Democratic Republic of the Congo, and Brazzaville, Republic of the Congo. However, the newspaper reported that the flight may take longer, which would give FlyNiki an edge on speed.

FlyNiki expects its new flight service to be most useful for airport transfers, rather than a viable option for regular trips between the two cities. Driving from Vienna to Bratislava takes about 53 minutes, according to Google Maps.

And as we all know, air travel takes longer than flight time alone. Considering how long it takes to drive to the airport and get through security, the flight is unlikely to save any time.

The world's shortest domestic flight is in Scotland between Westray and Papa Westray islands, and can take as little as 47 seconds.
