How much do you want to pay?

S-T, the only real solution is the parking garage across from the terminals. $2.25/1/2 hr last time I was there.

Depending on how long you're gone and how much you want to pay, there's L-T airport parking, and a few remote parking lots (one near the AC hangar where the FedEx aircraft park - earns AC miles) and another under the Oak Street bridge S. of Marine Drive in Vancouver (there's a coupon for this).
