I had a great set of flights this week with US, all in F; plus some good experiences with my new annual Club membership. I was wondering whom at US I could contact about the lack of meal service on 4+ hour transcon flights at dinner time. I mean 8:30pm Dinner flight is not a "red eye" and I did get a full lunch LAS-CLT. The 8:30 PHX flight is that last flight out of MCO and does deserve meal service!! The FA told me that lunch had been served on the flight to MCO, I mean really, is this the best US can do??
