Flying ATL-ORD-DOH on New Years Eve arriving 4pm into ORD and departing to DOH at 6:35pm. AA award ticket on AA F and QR J. I assume we arrive T3 and depart T5. Assuming on time arrival into ORD, what time do we need to depart Flagship Lounge to head to T5? We have clear and precheck it that helps. Thanks.
The second variable (beyond the timeliness of your flight from ATL) is the amount of time required to check in and clear security. Business check in for QR at ORD is typically pretty quick. However you cannot count on the availability of PreCheck at T5. There are PreCheck lanes at T5 but staffing seems to be an issue. I have been through security at T5 where the PreCheck lanes are open and functioning properly and have cleared security in 5 - 10 minutes. I have been there where you go through the PreCheck lane and get dumped in with everybody else and have to be cleared as if I did not have PreCheck. I have been there and the PreCheck lanes are closed.
Personally I would not get to T5 later than 90 minutes before departure. You could cut it a little closer if you don't mind the risk.
This has been discussed in the following thread in the USA - Midwest forum. There are people there who have more experience than I have with T5. You might want to post your question there.
