The pass was released Wednesday but was temporarily suspended due to the huge influx of traffic. The company tweeted about the issues getting reservations and has a warning on the website noting there are delays "due to persistent instability of our reservation system and higher traffic on our website."
The passes aren't transferrable and still require you to book a ticket to travel. The lucky pass holders can begin booking economy class tickets for their summer trek on April 19.
At the time of publication, the pass is available again, but you obviously want to hurry if you're trying to get your hands on one. They're more slippery than a Ziploc bag full of poutine gravy.
