Discounted flights from Detroit to Calgary are available for September travel, starting well below the typical $350 roundtrip price. Dates are limited, but there are even a few nonstop options available.
Calgary is a great jumping-off point for a September trip to the Canadian Rockies. Banff is about 90 minutes away, with Lake Louise, mountain hikes, scenic drives, and incredible fall scenery all within easy reach. September is an especially beautiful time to visit, with changing colors, fewer summer crowds, and crisp mountain weather—plus the possibility of an early dusting of snow at higher elevations.



Availability is limited, so this is one where you’ll want to check the dates below and see if anything works for your schedule.
