Flying tomorrow on separate ITN...

CLT-JFK (AA) - booked via AA
JFK-DOH (QR) - booked via AY, separate ITN.

We are checked in/pre-check to JFK. 5-hour layover in JFK. Plan to hang at the new FC lounge.

"Checked in" to DOH, but do not have BPs. Printout says to go to check-in counters no later than 2 hours before scheduled departure. We have no plans to exit security just to pick up BPs.

Can AA at FCL do check-in for QR? Anyone have experience here?
