We took a domestic flight from Lima to Cuzco through Viva air. They deliberately split up all seats bought together so they can make money on upgrades. There were entire families with children under 5 years of age that were sat at opposite ends of a half empty flight. They would not allow these families to sit together despite the flight being nearly empty.
Also, sitting at the gate or even while boarding our return flight the staff will approach you if you are white or look like a tourist and charge you for your bag even though it fit the dimensions and weight limit. As the woman was charging me for my 1 bag being ‘too large’ a women with a bag twice the size of mine walked by. I said something to her and the woman stopped her but she said something in Spanish and was just left to go and board the flight. On top of that, they allowed my husband to board the first flight with his bag, but forced him to pay for his bag the second return flight! The tag from the first flight was still on his bag!
This is the worst economy airline I’ve ever flown. The savings are definitely not worth it considering they will charge you for everything and anything that they can. I felt particular disappointed in the very apparent racism that my husband and I experienced. We noticed only westerners were being pulled out of the boarding line and forced to pay for extra luggage. There were people passing me in the boarding line (seemingly locals) with 2 bags and bags that far exceeded our 35 liter backpacks that we each had.
I certainly would never recommend flying Viva Air. You won’t save anything by the time they finish charging you for the most basic things. Personally, I would fly with an airline that treats their customers with respect and dignity. Very disheartening experience to be singled out and mistreated.
