Allegiant Air's new twice-weekly flight between Appleton's Outagamie County Regional Airport and Phoenix-Mesa Gateway Airport operates on Thursdays and Sundays.

Allegiant Air has begun twice-weekly nonstop service between Appleton in Wisconsin’s Outagamie County and Phoenix-Mesa in Arizona.

The carrier is offering introductory one-way fares from $99.99 between the cities. The Allegiant Air offer is not available on all flights and must be purchased by November 16, with travel to be completed by May 15, 2012.

Reservations may be made through or by calling Allegiant’s call center at 702-505-8888. A “convenience” fee of $17.00 per passenger is included in the introductory one-way fare. A fee of $14.99 per segment will apply when purchased through Allegiant call centers. Purchases made at any Allegiant airport ticket office will not incur a convenience or call center fee.

This is a McDonnell Douglas MD-83 of Allegiant Airlines, which is a subsidiary of Las Vegas-based Allegiant Travel Company. By the end of 2011 Allegiant Air will have at least 60 MD-80s in service, as well as several Boeing 757s

“Outagamie County is proud to build and expand our partnership with Allegiant. In addition to vacation destinations Orlando-Sanford and Las Vegas, Allegiant will now serve Phoenix-Mesa,” says Thomas Nelson, Outagamie County executive. “This expanded partnership will serve our community well through competitive low-fare air service and by attracting new passengers from outside our area thereby providing an economic shot in the arm to local businesses.”

Allegiant Air’s new flight between Appleton’s Outagamie County Regional Airport (ATW) and Phoenix-Mesa Gateway Airport (IWA) operates on Thursdays and Sundays.

The flight is timed to leave ATW at 7:35 p.m. and land at IWA at 10:30 p.m. local time. In the other direction, Allegiant Air’s flight is scheduled to depart IWA at 2:35 p.m. and touch down at ATW at 6:50 p.m. local time.

Allegiant Air began serving Outagamie County Regional Airport in August 2008, initially offering service only to Las Vegas.
