Worst possible experience. They try everything to make the customer feel unhappy. On my journey I passed up to 10 airports in Europe and South America before I came to fly with Viva Air. Suddenly things are not fine with my carry on luggage or how I had packed my hiking bag (checked in). If anyhownpossible avoid this company and don't get blinded by presumeably low booking fees as they will be blown up by unnecessary and artificially inflated side costs for checked luggage/printing ticket etc. etc.
Good job Viva air you'll be out of business soon and for the better.
