My biggest issue with UC is the "hit or miss" aspect of it. The clubs are not consistent even within the same airport. Will there be hot food? Will there be salami? What time does it come out? What time does it end? What happened to hard boiled eggs? Is there one soup or two? Did I arrive in time to try a nice sample at, say BOS, or am I too late or too early?
If United would ever copy anyone, I wish they would copy Delta and how they are able to keep food flowing and fairly consistent at all of their clubs.
