The recommendation was to fly into Portland, as cheaper than Augusta--still not inexpensive, but better. And like a good girl, I went on the Web site for the current travel vendor for my agency, picked my flights, and got it set up. Did this back in June, in fact, and I have the confirmation email. Good thing, too.
Today I discovered a friend of mine will be visiting her parents in Maine that same week, so if I can come in a little early, I can hook up with her and her husband and do a little sightseeing, or just hang around the lake at her parents' place, or whatever. It'd be nicer than flying in, attending the meeting in Yet Another Government Office, and leaving, which was the previous plan--especially as this will be my first time in Maine.
So I went back to the Web site to see if I could change my flight, and it says "You have no upcoming trips". And "You have no cancelled trips". "Past Trips" shows my trip to Denver in June, which is the only travel I've had since this vendor took over in April.
On further investigation, the Delta Airlines site does know about the reservation, but I can't change the flights there because the ticket doesn't get paid for until right before the trip. I finally dug out the vendor's number and called their Help Desk, and they can see the reservation in their system--it just doesn't show up for me. The Help Desk had me send them a screen shot, and they say they'll get back to me.
