Want to travel cheaply between the cities and towns of Mexico?
Fly with Viva Aerobus – Mexico's version of Easyjet. The seats are basically a free for all but there's good legroom, comfy chairs and if you book the special VIP pass (their equivalent of speedy boarding), you get to avoid the queue and choose your seat first.
They fly all over Mexico (and even to Texas) and are cheaper than their rivals: Aeromexico. Plus you can just turn up at the airport and book a ticket for the next flight – how much easier can you get?
