I booked a ticket RNO-DFW-PHL departing 11/6 returning 11/11 for my 11-year-old and I. I noticed that the record locator had changed after we arrived PHL. I called the EXP desk and was told the reservation had been split and that it was done by "someone at Reno airport." Doesn't sound right to me. Why would someone at a local airport make such a change? Any thoughts? Has led to an interesting discussion about the upgrade list, but that's another topic.
