New direct airline routes are a traveler’s dream: They often offer significant cost and time savings. Direct flights also make it easier to visit lesser-known destinations – and trending places – without the hassle of a connecting flight.
And good news for winter 2025 trips: Several carriers will launch new direct routes (some seasonal; others year-round) from the US to domestic and international destinations. Here’s what to know — and how much time and money you’ll save.
New domestic airline routes for fall and winter 2025.
These new direct airline routes within the US are just the ticket for a fun fall or winter getaway without losing a travel day in an airport. They skip the transfer and offer serious savings, which means you’ll have more to spend on hotels and other travel expenses.
Here are a few of my favorite new domestic flight routes, and what you can expect to save both time- and budget-wise.

Inaugural flights often come with quite a splash, especially if they’re to international destinations. These airport celebrations are usually attended by members of the media and airline execs, and often passengers too. Expect ribbon cuttings, photo opps and sometimes even souvenirs and refreshments.
