Book your spring or summer trip now and save big! So-called "full service" airlines like JetBlue, American, and Delta have lowered fares for domestic travel to just $22 one-way or $43 roundtrip on several routes. United also has some super low fares, which is all in response to the ultra-low-cost carriers Frontier and Spirit lowering fares on even more routes to these same rock-bottom prices. Peak summer travel is available!

For fares listed below, I've kept this round-up around the $100 mark or less, but there are other great deals on flights to airports all across the nation for under $150 roundtrip. So, make sure to see what's available from your local airport here.

All of these fares include a carry-on bag plus a small personal item except United which only allows for an individual item that fits under the seat in front of you. The first checked bag is $30 each way.

Seat Selection

Seat assignments are not included with these fares, seats will be assigned at random upon check-in or you may be able to pay a fee to choose a specific seat.

Alternate Fares

The upgrade to a Main Cabin Economy fare varies greatly depending on the route. Some routes can be upgraded for as little as $30 roundtrip, but we've seen others where the difference in price is around $200. This type of fare includes advanced seat selection and allows ticket changes/upgrades for a fee. On United, this type of fare also includes a full-size carry-on bag, whereas Basic Economy does not. The first checked bag fee is still $30 each way.

Some routes may have similar or slightly lower fares on Frontier, Spirit, or Sun Country but these airlines only include a small personal item at the lowest fares, and you'll likely pay more in the end if you are unable to travel that light.

Example Booking

As an example, I found a flight departing Boston BOS on Wednesday, July 8, returning from Ft. Lauderdale FLL on Saturday, July 11, for $43 roundtrip.
