Another thing to watch out for. Just this past week I received an email invoice and itinerary for my deadhead from HLN to KIX. Looked at it and got the locator number and went to the carrier website to choose my seat. The more I looked the more I realized something was off. Checked more closely and realized that Corp Travel had the ticket booked on the wrong day. If I had just let it go, thinking that the ticket had been booked correctly, I would have been a "no show" for the ticket that was booked and not had a ticket when I showed up at the airport for my deadhead. Take a look at those emails as soon as you get them. When I called to have it corrected there was only one seat left in FC for the flight I needed.
