That's the outfit to use. They land right in Canmore and it's about a 20 minute ride to Banff from there. Depending on your plans, a Canmore based rental car company will pick you up, or maybe if you're at a Banff hotel, they'll come fetch you from the helipad. Taxis are cheap and plentiful as well. If you rent a car from Canmore, you'll need a Nat'l Park Pass as well - budget for it, it ain't cheap depending on your length of stay. Don't forget to plan an alternative in case weather doesn't cooperate. Also, you'll have to get from the Calgary Airport Terminal around to the west side of the airport to pick up your chopper ride... Alpine's phone number is: (1-403) 678 4802.
Have a great trip! It's truly God's country. I'll be there in Dec. m'self.
Cheers
