Is the best for construction updates. Its going well! Esp with the chase T2 lounge open in Dec 2024 finally a reason to get there early!
However, until T1 is done, there won't be a 'continuous walk' from T2 post security to T1 areas post security (Southwest) so any lounge visits at T2 will require you to go in, lounge, and then leave and walk post-security over to T1, re-do security and get in.

Will be that way for a few more years until T1 is done.
