Memphis to Orlando $34 Roundtrip for Late Summer Travel

Frontier is back with another round of $39 roundtrip fares. Since Memphis has a slightly lower departure tax, you can fly from Memphis to Orlando for just $34 roundtrip. For this route, travel is valid on Mondays, Wednesdays, and Saturdays, starting in mid-August through early September. For example, I found seats departing Memphis MEM on Wednesday, August 15, returning from Orlando MCO on Monday, August 20. Keep in mind, Frontier charges extra for any bag larger than a small personal item. Checked bag fees for this time period start at $30 each way. Larger carry-on bag fees start at $35 each way. Sale ends at 11:59 pm ET, on July 4th.

Dallas to Richmond $126 Roundtrip for Summer/Fall Travel

Fly from Dallas to Richmond for $126 roundtrip on United. Travel is valid on a few dates this week and again from late August through mid-November. For example, I found seats departing Dallas DFW on Saturday, August 25, returning from Richmond RIC on Tuesday, August 28. Only a small personal item is included in this Basic Economy fare. However, the regular economy fare is much higher so if you can handle getting a random seat assignment, I would suggest to buy Basic Economy and pay $25 each way for a checked bag, if necesarry.

Portland to Palm Springs $156 Roundtrip for Year-Round Travel

Fly from Portland, Oregon to Palm Springs for $156 roundtrip on Delta or United. Travel is valid year-round, with a 14-day advance purchase required.

I was able to find seats on Delta, departing Portland PDX on Saturday, December 1, returning from Palm Springs PSP on Tuesday, December 4. These are Basic Economy, but Delta will include a regular carry-on bag plus a personal item. United only includes a small personal item, but has better availability. If you want to fly nonstop, you can try Sun Country's new service on Sundays or Thursdays, starting November 1, for $167 roundtrip. Checked bag fees are $20 each way on Sun Country. Larger carry-on bag fees start at $25 each way.

I was able to find seats departing Los Angeles LAX on Friday, September 14, returning from Mexico City MEX on Sunday, September 23. Perfect for a week long trip over Mexican Independence Day. You can pay even less by booking two separate one-way fares and paying in pesos with a no foreign transaction fee credit card.
