Hi there! My name is John, and I have booked a flight ticket for my family vacation. As my baby, who is only 1 year old, is travelling with me, I want to make sure that he travels in full comfort. I just wanted to know that does Volaris charge for strollers and how soon I will have to inform them of this service. If any of you has gone through this situation, kindly help me.
