JetBlue Airways announced new seasonal service between Anchorage and Portland, starting June 18. The Anchorage-Portland flight will operate daily through Sept. 8, 2015.

The Anchorage-Portland nonstop marks the third city the New York-based carrier will serve on a seasonal basis. JetBlue starts its summer-only service from Anchorage to Seattle and from Anchorage to Long Beach on May 16. These flights also will operate until Sept. 8.

The airline is offering introductory fares of $99 each way between Anchorage and Portland for travelers who purchase their tickets by Tuesday, Jan. 13. Anchorage-Long Beach also is on sale for $128 each way (nonstop) and Anchorage-Seattle for $97 each way.

Like the Anchorage-Seattle and Anchorage-Long Beach flights, the Anchorage-Portland flight will be a late-night "red-eye," departing at 11:59 p.m. and arriving in Portland bright and early at 4:35 a.m. The northbound flight from Portland departs at 8:49 p.m. each day, arriving in Anchorage at 11:29 p.m.

In a competitive move, Alaska Airlines dropped its one-way fare from Anchorage to Portland from $170 each way to $118 each way. On the return segment (Portland-Anchorage), only one date (June 28) was available at the lower rate. During the summer, Alaska operates three nonstops each day between Anchorage and Portland.
