How much time to leave between flights in America?

[PLANT]

For the following itinerary not enough time from SFO to get on flight to LAX?
Have to collect bag and re check in?

Does travelling UA mean bags will go through to next flight?

If this is the one PNR then you would be "protected".

64 minutes meets MCT by 14 minutes.

Logistics are you exit T3 and head strait out for the next 'Red line' train.

Go one stop to T2, head into the terminal and pass security, head to your AA gate.

This would be a safe option to make flights with 1 CHECKIN bag :

Miami (MIA) to Los Angeles (LAX) - Sat, May 10

American Airlines Inc. 1375 Dep: 7:00AM Arr: 9:15AM 5h 15m Boeing 737 Coach (N)
Layover in LAS 1h 48m
United Airlines, Inc. 1070 Dep: 11:03AM Arr: 12:20PM 1h 17m Boeing 737 Coach (L)

--------------------------------------------------------------------------------

Los Angeles (LAX) to Kona (KOA) - Sat, May 10

United Airlines, Inc. 1228 Dep: 3:05PM Arr: 5:53PM 5h 48m Boeing 757 Coach (L)
Layover in HNL 1h 37m
Mesa Airlines, Inc. 1007 Dep: 7:30PM Arr: 8:10PM 40m Canadair Reg. Jet Coach (W)

How does this PNR "protected" work over there...they hold the plane?
Does that only apply to UA to UA not AA to UA?

Serfy I could walk to T2 with bag but will I be able(have) to collect checked in bag and check it in T2 right?
Then security could potentially hold me up no?

ITA does not show a same day itinerary as I have posted but a more expensive $700 option?

Does the above itinerary involve 4 x $25 checked in baggage payment?
