Their service just keeps getting worse! They push for you to get the app for easy check-in, however, a new policy came in (info given from a volaris representative) where the app will automatically assign you your seat. The problem is if you have a different reservation number then your partner or family members it will not allow you to sit next to them unless you pay a fee. It will assign you in the middle or the end of a row with random people and if you try to move up one row it will still charge you! Also, if you check-in as soon as it is open you will be automatically assigned to the last row and the system works it’s way up. Calling their customer service phone is a waste of time, they will NOT help. This last trip the app would not allow me to check-in everyone, there was a glitch and it only gave me 1 boarding pass out of 3, I called volaris and they asked me try online instead of the app. I listened and a system notification came up that said “please call our customer service for assistance” I read it to them and they told me to try again in a few hours and hung up. Lastly, the flight prices in the app are not the same as the website so make sure to check both, one may give you a cheaper price.
