I think I didn't realize it was airports only. I just flew into PDX last week and there were a ton of people waiting for rides, since they're still matching riders and drivers, rather than doing PINs, but I did only wait about 5 minutes. I've had some close calls in the past few months where the pickup time was looking like a half hour or more, but usually ended up less than 20 minutes. Once things get back to normalish, priority won't matter much at the airports I use because they'll go back to the PIN system, but priority for pickups from home would be useful.
