Will I be able to make it to my next flight??
 

I will be arriving at Washington IAD (Dulles) at 15:30 from Doha. I have to catch my next flight to Orlando (United Airways) which departs at 17:30. Given that Qatar airways lands on concourse B and United leaves from Concourse C Will I be able to make it in 2 hours. I will have one checked bag and will have to go through US citizen immigration. Please advise as this is the last flight from IAD to MCO.

If you are on a single ticket, this is a tight but doable connection. If on separate tickets, I would not attempt this as missing the UA flight likely means purchasing a new ticket to MCO.

The concourse issues are less important because you will go through CBP at International Arrivals, either recheck or drop your bag after CBP, go through TSA and then head out to your United gate on either Concourse C or D (they are the same very long concourse, but the access is different).

If your inbound flight is late and you are on a single ticket, QR will need to rebook you and take care of your hotel.

I’d guess you are on separate tickets in which case I would not attempt this. Budget for a night at the Marriott or take your chances.

Thank You for the replies. Yes I am on separate tickets. A part of me wants to take up the challenge and give it a shot but you guys are right. Marriot it is.
