I did the walk from T1->HR last night without bags after dropping my rental car off and then HR->T7 with bags this morning because I was tired of waiting for the shuttle. It was a nice 10-15 min walk with bags and ~7 without. FAR better than sitting in the LAX traffic in the shuttle. The only inconvenience, and it was very minor, was construction on the arrivals level getting across from T1 to T7, but it was completely manageable.

BTW - If there are any UA folks here that need to check in at the airport or check bags, give yourself way more time than you'd think. I hardly ever check bags, its against my religion, but today I had no choice due to the items in my bag. The scene in the premier check in was normal LAX unpleasantness X 10 - absolute chaos.....50% of the kiosks broken, the other half only had one UA employee floating back and forth having to deal with issues and one very slow moving non-UA employee pulling bag tags off the back of the machine, and only one person in the live check in dealing with the non kiosk issues. As a 1K it took me 45 minutes just to drop my bag and there were dozens of rather frustrated other UA elites in the same boat. First world problems, but not a good look by UA this morning....plan accordingly.
