Frontier's Delaware-Chicago flights to return

Frontier Airlines reports it plans to resume its seasonal service between New Castle Airport and Chicago-Midway in summer 2015.

In July, the airline seasonally suspended four of its remaining six routes for the winter, with no promise of whether they would resume any of them at winter's end. On Monday, Frontier spokesman Todd Lehmacher said of the Chicago route, "It's a route that we've flown, and we plan to resume it this summer."

He would not specify on what date service would resume. New Castle Airport Director Stephen Williams said the news is consistent with what Frontier has been saying, that the route suspensions are for the season, not necessarily permanently.

Williams said the airline needs no permission from the airport about stopping or starting a route. Williams said he would guess a summer restart would begin right before Memorial Day, but could begin as late as July 1.

"It's a bit of good news," Williams said.

Frontier made the Midway-Delaware announcement as a footnote to the rollout of its service at Chicago's other airport, O'Hare, which starts Monday.

The airline is seasonally suspending routes to Chicago, Denver, Atlanta and Fort Myers, Florida. Those suspensions were originally scheduled to take effect in December, but they were moved up to October, meaning some passengers needed to seek adjustments or refunds to their tickets.

Service to Detroit will be discontinued after Sept. 21, according to the airline's website.
