All a check in agent needs to do these days is get one thing right. When you print your own boarding pass and check in at a kiosk, all the agent needs to do is put the correct tag on your bag. Our check in agent today couldn't even manage that. It wasn't until our bags didn't arrive in DC and we looked at our baggage receipts that we realised that she'd put someone else's tags on our bag. Someone else who was going to Tampa Bay.
I've hated United so much for so long that I would have thought it impossible for me to hate them more. I was wrong. Very wrong.

They give you a website to check the status of your bags (http://www.united.com/bagcheck) but all it tells you is that your bag has been found and is in transit to you. But you still have to call and talk to an agent to find out the specific flight it was put on and when you can realistically expect it. It's one thing not to have information on the website that they don't have, but what's the sense in having the website if it doesn't tell you the information they have and you want?
