At the most recent LAWA meeting they approved the closure and complete demolition of T5.
T5 is closing on November 1st.

When asked about the current airlines at T5, LAWA said that:

1. Jetblue is going to Terminal 1
2. Spirit will check in at Terminal 2 and fly out of MSC South
3. American will "fly more out of TBIT"

A couple other interesting points:
1. In response to a question the LAWA CEO said it is "not yet decided" whether the incumbent airlines will return to T5 when it is complete.
2. In mid-2027 they will determine if the project is on schedule enough to complete in time for the olympics, if it is not on schedule they will switch to a Plan B and only open 5 gates, instead of 15, in time for the Olympics.
