My elderly father and I are transiting in Miami. We are arriving from Doha on a Qatar flight and departing from MIA to Indianapolis on an AA flight. The flights are booked on separate tickets (1 QR ticket and a separate AA ticket). We will have to go thru customs and collect our baggage upon landing and then get over to the AA counter to check in with our 4 bags. We are flying business from Doha and first class to Indianapolis. We are not sure how far we will have to go with our suitcases and if it far to walk, my dad may need some assistance. Do you offer this service to help with our bags and getting over to AA? Thank you.
