Leaving from Pierre (PIR)

When to book
For a trip of 158 miles, booking 2–4 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go

- Screenshot your fare before you enquire — prices move, and a saved fare helps our team match or beat it.
- Flexible dates? Search a few days either side — one day can change the fare a lot.
