I used to live in the valley. BUR was very convenient. Now I live near Century City and it just sucks going to LAX. Traffic is so unpredictable in both directions, freeway and surface streets. If that isn't bad enough, lately once I hit the terminal area it takes 20-45 minutes to make the loop. Recently a bunch of us got off the shuttle and hoofed it to the other side. Doesn't matter if I park in main parking or off site and take a shuttle, I'm still stuck in the terminal traffic mess. I don't know why this is. The construction is minimal.
I don't travel a lot but I am considering using BUR from now on. The time savings and ease of travel once I reach the airport area is significantly better even if there isn't a pre-check line. (I haven't used BUR in a long time and don't know what's available.) Getting to/from home doesn't seem like it would be any worse, and in some cases it could be better.
Anyone else using BUR or considering it even though you may live closer to LAX?
