[QUOTE=MariaSF] Airports with several terminals, that require passengers to take a bus to go from one to another. PHX comes to mind.

Amen to that one. You have to claim bags and take a shuttle bus in SYD when switching from international to domestic flights/terminals, then recheck your bag. This morning one woman had 45 minutes from when she boarded the shuttle bus to her domestic flight. I had a little over an hour - figured all was fine. Then we sat there 10 minutes or so, filling up with transferring passengers. The lady with the tight connection asked the driver if we would be departing soon. "No worries - you'll be just fine ma'am!" They closed the luggage bins on the bottom of the shuttle bus, and then a family came with many children - father says "Can you carry 18 more bags?" "Sure" says the driver, reopens the bins, stows all of the bags, and we finally take off. We get to the domestic terminal, and yep, the lady with the short connection's bag is at the bag of the bin since it was one of the first on, so it's one of the last off. She goes to check her bag, and now that she's within the 30 minute window, they won't check her bag and tell her she'll need to take the next flight an hour later. She was so frustrated, she was almost crying. And then the agent told her that he would be happy to tell her his name, but that he no longer wanted to hear anything else from her - she could talk to a supervisor at a next level. And then he repeated a couple more times that he no longer wanted to hear anything else from her. I can understand wanting to defuse an emotional situation, but to me his attitude just seemed to escalate it, on top of the "sure, sure, all will be fine" attitude of the bus driver. All of this drama brought to you by separated terminals.
