update:
chat - they say they can't handle requests like this through chat
email - sent 5/2, still waiting for a response (beyond the automated "thank you for taking the time to contact us" response)
calling customer relations - got a message saying to call back during their open hours, but i did call within those times, so not sure what the issue is.
thanks for all the responses so far. fyi
rove312 i originally tried a flightaware.com printout, but it was rejected and they told me it has to come from the airline.
