hello, I might have an AA to UA connection coming up (different PNR's).
Looks like AA mainline (T4) to UA (T7).
1hr 20min time between flights.

Is this too risky? (I can definitely change the UA flight to a later one if I miss my original flight.)

However...if everything goes perfectly on time, can I make the connection in under 1 hour of walking, running, etc?
Not familiar with LAX.
