When checking in online, the mobile boarding passes for both my tickets do not list the gate. This means I have to recheck in when I get to the airport to figure out where I'm going. If this could be fixed it would be greatly appreciated.

Even though there were many delays in Seattle due to fog, staff remained calm and helpful getting all the people who would miss their connections scheduled.
