I'm pretty sure that feature disappeared a long time ago, prior to this refresh. If you want a PDF you should still be able to get it from CheckMyTrip.

Something else I noticed is that the new site won't let you book some routes with partner airlines. You can search for HKG-LAS or MNL-LAS just fine. Both of those will send you to LAX and then give you an LAX-LAS flight on AA. But if you try to search for CEB-LAS, it won't let you choose LAS as a destination, which is completely bizarre.

And this problem is not related to the search results. It is the front-end website software that is blocking you from entering LAS as a destination in the search box if you put in CEB as your departure airport. When you type in "LA" the only city that shows up in the list is LAX.
