Yes, flight IS a problem for Reno. But only part of it. It's hit and miss snow record is a bigger problem really.
I'm really not sure what they're after. As pointed out by others, Tahoe has mostly been a regional destination, not a national ones. Snow record will make sure it'll stay that way. That's pretty much the end of the story.
I'm one of those who fly across the country to ski Tahoe. But that's because I used to live in the region and already know what the skiing is like. Otherwise, I doubt I would chance an expensive flight, an expensive SUV rental, and some expensive lift tickets to "sample" the 10 ski areas spread across 2 hrs from each other!
Colorado and Utah has the snow record for most years. You can book a vacation in Jan/Feb and pretty much sleep soundly that there will be snow there, enough to cover up most of the rocks. And if you're like me, you'll go to CO or UT in April and enjoy quiet slopes, cheap lodging/rental car, and still have great snow coverage and often fantastic conditions too! Tahoe? Not so sure about the coverage part in Jan/Feb. Then not so sure about the condition of the snow by April. So, it's pretty risky to book in advance. But far too expensive to book last minute flights. Result of which? Not going there...
I've skied there for a couple years. So I know exactly where to go when it's too warm. I know where to go when the cover is thin. But for a once a year visitor, if they hit a less than ideal year, they're not coming back! Tahoe is really better for locals who can chase the best condition by driving up at the drop of a hat.
If the flights are more convenient, then ex-pat like me might come more often. But I think I'm very much a minority, and NOT the demographic the region is after.
