I also have a potential problem with name formatting. We were due to fly LHR-DTW-MCO, then DL changed our leg to Orlando with a 7-hour layover in DTW. I was able to change it to VS on a non-stop itinerary, much better. But when I got confirmation from VS, they had combined our first and middle names on our booking. VS told me I needed to call DL, since they originally made the booking. DL said there is no problem, as the ticket matches out passports.

Later, I found that the secure traveler info for our flight in DL's site also combined our first and middle names, although the names in our profile, containing the GE number, are correct. It's only the GE info on this specific booking that is wrong. DL had a number to call if pax names don't match the secure traveler names. That agent told me there would not be any problem.

I don't believe that - I think there might be a problem at check in, or GE will not work when we arrive, but I don't know what else I can do. We are flying on Sunday.
