I received yet a different one:
Use code LAXFALL24 and take an extra 20% off Budget Parking or 15% off select Terminal General Parking to get on your way faster.
I use the Economy Parking facility several times a years, so as a semi-regular customer I seem to no longer receive discount offers for that facility.
ETA: I just read the fine print, Economy Parking is included:
Redeem promo code LAXFALL24 for 20% off Budget Parking; 15% off Economy Parking; 15% off P1 and P7 Terminal General Parking; 15% off Terminal Premium Parking.
