DES MOINES, Iowa (AP) -- Discount airline AccessAir has grounded its fleet while it undergoes a Chapter 11 bankruptcy reorganization.

Service was to end by early Tuesday. Customers holding tickets may seek a refund or keep their tickets and get two for one when AccessAir begins flying again with new routes in about a month, officials said Monday.AccessAir began on Feb. 3 with service between Des Moines and Los Angeles and New York for as low as $99, with stops in the Quad Cities along the Iowa-Illinois line and in Peoria, Ill.

President and chief operating officer Rich Musal said customers didn't respond as expected. The airline's best month was November, when planes were about one-third full, he said.

Musal said the company will "come up with routes people want to fly." AccessAir is considering flying to Las Vegas, Orlando and Phoenix. Musal said flights to Colorado Springs and Los Angeles will continue.
