I booked a flight for my cousin and he is having a family emergency. As a student, I helped him pay his flight with United and paid with my CC. After making the reservation few minutes back, I found this "The credit card used for this purchase must be available at check-in." Is there a way arond? I am not going to travel or going to be at the airport, no way I can show my CC during his check in. What should I do?
