Wow. Thank G*d again for FT. I was trying to get my SO on an ATL-SJO itin that I had booked in F SkySaver on DL months ago. Saw SS outbound on CO connecting through IAH, which was fine. The return was a problem. No avail SS or SC near my departure time (an early AM was avail). So, I tried the search on CO.com. Sure enough, boom, the same flight I was on for the return shows their equivalent of SS in F. I call DL, explain what I found, they say they see it too. Txfr to online help desk, who waives the fee and tickets. Done. Would have never thought if it if not for smp9778's post. Thank you. Thank you. Thank you. FT rocks!
