My daughter recently departed for a year of study abroad in Chile. The organization told her she could pick up her visa at the Santiago airport. Upon arrival at Delta check in, she was informed that she couldn't fly because she did not have a visa for a stay over 3 months. We had to reschedule her flight for 3 months from now and will have to again reschedule it now that she has her visa, all for the modest fee of $500.00. They will squeeze the money out of you any way they can. Oh, and by the way, they lost one of her bags on the flight so now she has to take a 4 hour bus ride to the nearest airport tomorrow to pick it up. They wouldn't even deliver it.
In the future, I will pay top dollar or drive in order to avoid Delta.
