One ticket DSM>LAX via PHX.
Separate ticket, same day departure, LAX>PPT and the return.
Same ticket as the first segment, same day departure, LGB>DSM via PHX.
6 hour cushion between arrival to LAX and departure on the outbound. 8 hr cushion between arrival to LAX and departure from LGB on the return.
All flights using miles, taxes paid with a CSR. Would I have any trip delay/interruption protections in the event that I was delayed getting to LAX, causing me to miss LAX>PPT, or if I was delayed getting back to LAX, causing me to miss the return flight to DSM from LGB?
