I will add my welcome to ILM. As a refuge from SEA, it took a little while to get used to the smaller airport with limited choices to the rest of the world. If upgrades are your goal then you really do need to re-up with DM. We now have F seats on most of our US flights (and all to CLT I think). Yes, there are a lot of CP on the flights so I guess you won't upgrade very time, but you probably will enough to make it ok. I don't fly to LAS much so I have to let others comment on that segment - my guess is that it's a tough upgrade.

I do fly US to Europe once in a while and I agree about the service, but I am willing to overlook that for the envoy suites which I think are great.

Don't forget the we have the CLT - MUC flight also.

The only other choice in ILM is DL to ATL. Not a great choice as it is all coach service on ASA and they really struggle to operate an on-time and MX free schedule.

One minor correction to a post able - US will operate LGA 2x a day.

Feel free to PM me if you need more ILM info.
