I need to purchase 4 flights from BNA to LGB next week.  I’ve probably confused myself by overthinking, but would like advice how to achieve this purchase with points, flight credit, and gift cards.  I won’t know the exact price until flights are released on Thursday, but I’m estimating cost will be $375-$450 each.  I’d like to pay my flight with points.  The other 3 flights would be paid with the $150 flight credit and 2 SW gift cards of $500 each. Since SW only allows 3 types of payment per transaction, I’m guessing I will need to split the 4 flights into 3 separate purchases:  one flight booked with points; one flight booked with the $150 flight credit and SW gift card #1 ($500), leaving a balance on the card of approximately $200; then the remaining 2 flights would be paid with the balance of gift card #1 (around $200), plus gift card #2 ($500), then using a credit card for anything cost remaining.  This plan would result in 3 confirmation numbers, resulting in needing to check in all individually 24 hours in advance.  Is there an easier way to do this?
