Domestic flight prices for peak summer months are getting cheaper in the US, with airlines offering deals on popular summer vacation destinations. For instance, JetBlue ran a “Spring Sale” which included some extremely cheap fares for flights to Cape Cod, Martha’s Vineyard and Nantucket which extended well into June, and other airlines had to match them to stay competitive. Furthermore, availability during peak summer months has been popping up for other US vacation spots like Myrtle Beach, South Carolina, and Destin, Florida. Travel website, Thrifty Traveler Premium, has released a list of some of the best summer flight deals, which include Jackson, Wyoming, which is on the doorstep of Grand Teton National Park, and St. George, Utah, which is the ideal gateway to explore Zion National Park. On the East Coast, a cheap flight to Portland, Maine, is a great jumping-off point to explore Acadia National Park and the entire Maine Coast. It is also possible to find peak summer flights to Hawaii, with Thrifty Traveler Premium subscribers seeing nonstops from Dallas to Honolulu and Maui drop to $437 roundtrip. Thrifty Traveler Premium assures subscribers that the best flight deals for summer travel can pop up at any time, and getting flight deal alerts sent straight to their inbox ensures travelers are ready to book as soon as they find them.
