Ok, seems like there is a built in browser in the app or standard browser is called upon for certain features like Seat Assignments and sometimes for when checking in.

However, the overall links in those sites - Home, Account, etc. do not revert back to the "app", but stay in the browser mode which leads to logging in again, since I never actually logged in on the browser itself.

Its probably the major flaw in the app right now. They should just have the menu bar at the bottom constantly, so that I can go back to the App itself after doing seat selection or so instead of being stuck in the browser mode. Anyone else figured out a better way to navigate around it?
