The sky train is fantastic. Almost hard to believe this is Phoenix and someone got it right.  But then there's news that when terminal 3 is connected they will be spending money to build a walkway to terminal 2.\n\nA walkway really? Hope it's a short walk at least, but aside from that, what about the West economy parking and the rental car facility?  \n\nI know it's not even in the budget right now, but they aren't even discussing it as part of the plan to make the airport truly connected the way it should be.  One would hope theres a plan for this. \n\nOtherwise, one poster brings to light a safety concern. Power outage.  What's the plan for fire escape, and trapped passengers in the summer heat? \n\nBut otherwise I've used the train twice, one for US Air and the bag check is great along with the location in terminal 4 at the gate level, and then once for Delta, term 3.\n\nTransferring to a bus wasn't the greatest, but the signage of where the terminal bus vs. rental car bus waiting areas are not clear. Lots of people including flight crews asking where the correct bus stop is. I answered, I thought you knew so I was following you LOL
