Amtran may expand their Tyrone service this summer from three to six days a week. Reportedly, CEO Josh Baker intends to ask for formal approval next month after alerting the board to the plan, yesterday. The service to Tyrone started last June as a pilot route that ran only on Saturdays, then expanded to a three day schedule in August. The expansion is being requested because ridership of the Tyrone route has increased, and has received positive input.
