Thank you so much, stephem.
For the life of me, even with my friend's PNR, I cannot find the fare basis. Perhaps because he has already initiated the cancelation?
But, I can provide the flight details, if someone can help (or point me to how I can do it, "teach a man to fish" style). They are as follows:
LAX-LHR-CDG (BA 1509, BA 0310) March 25 (arrive March 26)
ZRH-LHR-LAX (BA 0713, BA 0269) April 3
Date of Purchase: October 15
Thank you!
