I found seats departing Denver DEN on the inaugural flight, Tuesday, April 30, returning from Boston BOS on Saturday, May 4. This price only includes a small personal item.

If you're a Saints fan that is still upset about that blown call in the NFC Championship, why not fly to LA and tell Rams fans how you really feel.

Philadelphia - San Francisco $197 Roundtrip for Winter Travel

Alaska Airlines has some incredible cross-country fares in its latest flash sale. Fly nonstop from Philadelphia to San Francisco for $197 roundtrip. American and United are also matching this price for travel on Tuesdays, Wednesdays, and Saturdays, through mid-March, with a 21-day advance purchase required. United's Basic Economy fare is the most restrictive so I would recommend flying either Alaska or American. I found seats departing Philadelphia PHL on Saturday, February 23, returning from San Francisco SFO on Tuesday, February 26.

Boston - London  $368 Roundtrip for Winter/Spring Travel

Fly nonstop from Boston to London-Heathrow (LHR) for $368 roundtrip on Virgin Atlantic or Delta. This is a great price on legacy carriers competing with low-cost service on Norwegian from Boston to London-Gatwick (LGW). Since prices are similar, I would recommend flying into the more convenient Heathrow airport and enjoy a standard onboard experience on Delta or Virgin Atlantic. This price is for Basic Economy so there will be a $60 fee each way for a checked bag. I found seats departing Boston BOS on Wednesday, April 3, returning from London LHR on Wednesday, April 10. Other dates for this price can be found for travel through mid-May, with a 28-day advanced purchase and a 7-night minimum stay required. Travel to London Sundays through Wednesdays, and return from London Tuesdays through Fridays.

Tampa - Sao Paulo $521 Roundtrip for Winter/Spring Travel

If you've been dreaming to experience Carnival in Brazil, here is a great opportunity to make your way there on a budget. Fly from Tampa to Sao Paulo for $521 roundtrip on Delta. This price is available on scattered dates through May, with availability over Carnival dates. While there are celebrations in Sao Paulo, it will also be pretty cheap to purchase a separate domestic flight from Sao Paulo to the beaches in Rio, Salvador, or Florianopolis, where there are larger Carnival festivities. I found seats departing Tampa TPA on Friday, February 22, returning from Sao Paulo GRU on Sunday, March 10. Carnival falls between March 1 and March 9 and these flights will allow you to enjoy an extended vacation in Brazil.
