Pros: Volaris offers transportation to and from airports and if you want more you have to pay for it. We don't need snacks, movies, wi-fi, etc so we are fine not paying for them.
Cons: It would be good if Volaris would offer water without making a big deal about it. They will sell you a bottle of water but they should bring everyone a free cup of water on the flight to help deal with the dryness of the air.
Also the seats, like on most airlines now, are very cramped. So please be mindful when you recline. On this flight a woman seating in front of me reclined her seat and just about took out both of my knees. She seemed offended when I told her what she had done and asked her to look before reclining and give the person behind you warning. I didn't mean to offend her but she needs to be aware that taller people have their knees up against the seat of the person ahead of them. So if that person reclines it is going to hit the knees. So please be mindful of this space limitation when you are reclining.
