Last week flying CO: 1.) CO3212 BWI-EWR was delayed and I would miss my connection to CO45. Plat Desk changed me to AA non-stop. Arrived around the same time as my original plan. 2.) On the return, called Plat Desk and asked to SDC to an earlier MIA-EWR flight. The response:"No problem". 3,) Called today and asked for ORC on the original outbound flights, completed within a few minutes. I like these changes.
