Hello!
Last year I made 2 United flight reservations using reward miles and paid with DH's Explorer Card. Well, our flights are coming up and DH no longer has the explorer card.

On our reservations it shows that we get free checked bags, but will that still apply since he no longer has the card? Do they ask to see your card when you check your bag, not sure how all that works? I have an explorer card, but it is not the one used to book this reward flights.
Please help, our flights are coming up and I want to know if I should be prepared to check bags or we will all be taking a carry on.
Thanks!
