Getting into Montana is almost always pricey these days and the airports in the North West of the state are even more expensive.
Philly to Montana generally runs in the $550ish range for a decent flight on a legit airline, this saves you ~40% off that price and gets you there on Delta.
It's rare to see Montana drop below $400, and more rare to see only a single stop with a flight that cheap (out of Philly no less!). This is easily the cheapest price I have seen Philly -> Montana in the past 12 calendar months.
OT Email Supporter beta is now open, you should Sign Up to be notified when new Philly Ski + Snowboard flight deals come out (you also score a few un-published flight dates on each new deal).
Ski and Snowboard
Anyone looking to get to Big Sky can fly into Bozeman (also part of this Delta sale) for an extra $20 to shave off an hour of driving for those headed south.
For me I am headed north and I will be paying the extra $30 to fly into Glacier Park International easily one of the easiest spots to hit the PH. You guys who are already Email Supporters (as well as Pro/Am Beta testers) received those additional dates to your emails.
For those not interested in a PH road-trip, another great, down-to-earth AND much closer option is Teton Pass resort. $45 Lift Tickets day in and day out and plenty of serious terrain to make the trip worth your while (though you will have to hike to improve on the 1100ft vertical!).
Free Trips / Flights / Dates
While Pro/Am Supporters (paid) score a 2 hour head start and full availability, we just opened our Email Supporter (Free!) Beta that gets you a few extra dates that you won't see as a regular website visitor.
Book Your Flight
Here are some flight options for those of you who are NOT yet Supporters and did not already receive these dates (and bonus un-published options) straight to your email / phone:
Glacier Park International (+$30)
Reminder: Email Supporters receive a date or two extra in addition to the above, you should totally subscribe, it's free and having more dates sent to you means less searching / hassle. That makes booking faster / easier, and you usually get a better price.
