Been using United/Ted for years. Did you sign up for their frequent flyer program. If not, you should. As a member you can log in and check your itineraries often and make sure there are no time changes. Often there are some minor time changes and it's usually months before I get a phone call telling me. If you see something you don't like, you can call them right away and talk to them about it. Also, by being a member, you get lots of bonus points by printing your boarding passes at home. Even though I print my boarding passes at home, if you decide to check luggage inside the terminal, you still need to get in the eticket line and use the easy checkin machines. You need the credit card you bought your tickets with and a picture ID for check in (actually all adults need picture ID). United boards with the zone method, with zone 1 first, then 2, 3, 4 (and higher if the plane is larger). You get zone 2 if you or someone in your traveling party that you bought a ticket for has a window seat. Middle seat purchase alone gets you zone 3 and aisle seat purchase alone gets you zone 4. Keep in mind that if you buy more than one ticket, the zones go by the lowest seat assignment. For example, you buy 2 seats and book a window and aisle, both seats will have zone 2 of them. But if you buy a aisle seat only, that will be zone 4. Hope that isn't too confusing. It took me a little while to get use to their new seating rules. One of the things we like with United is that they are one of the airlines at the Disney resorts that participates in resort/airline check in for our departure. We don't use DME and rent a car, so we pick up our luggage on the flight down. But coming home, we go to the airline checkin and check our luggage at the resort and have done it 5 times and it works great. Hope some of this info helps.
