Low-fare leisure carrier Allegiant has announced its largest ever service expansion, driven primarily by routes connecting underserved cities to popular destinations.

The airline has announced 44 new nonstop routes, including 14 routes to three new cities: Chicago, Boston and Houston. Most of the routes are non-competitive, with no other airline providing service between those airports.

“There is a lot of leisure demand for cities that are regional destinations, and this route expansion will address some of that need,” said Drew Wells, Allegiant vice president of planning and revenue. “Also, this growth is about Allegiant being true to our mission as a company. We’re increasing the number of low-cost, affordable travel options for people who may otherwise be priced out of air travel.”

New seasonal routes to Boston Logan International Airport include services from Grand Rapids, Michigan (Gerald R. Ford Airport) from 7 May; Asheville, North Carolina (Asheville Regional Airport) and Knoxville, Tennessee (McGhee Tyson Airport) from 8 May, as well as Destin/Ft. Walton Beach, Florida on 14 May.

The new seasonal routes from William P. Hobby Airport include services from Knoxville, Tennessee beginning 21 May; Asheville, North Carolina from 22 May; Savannah, Georgia (Savannah/Hilton Head International Airport) from 28 May and Destin/Fort Walton Beach, Florida from 5 June.

Chicago Midway International Airport will gain six new seasonal routes meanwhile, with the first (to Allentown, Pennsylvania) beginning 14 May.
