In excellent news for Dallas residents in need of a little sun, salt and sand, at number 10 on our list are direct Spirit flights to the sleepy Mexican coastal town of San Jose del Cabo.

9. Fly from Fort Lauderdale to San Juan for as low as $203 round trip

Fort Lauderdale is already a gorgeous beach town, but if you ever long for somewhere with a little more history, then Spirit run super-cheap direct flights to Puerto Rico's capital of San Juan. Juan's exquisite Old Town is lined with colorful colonial houses, 500-year-old Spanish forts and shaded cafes, while down on the shore you'll find one of the Caribbean's prettiest (and oldest) harbors, flanked by a string of white-sand urban beaches.

At number eight, Fort Lauderdale residents have an alternative Caribbean getaway: the lively Jamaican resort town of Montego Bay.

Sumptuous resorts such as Round Hill and Iberostar look out over calm turquoise waters and palm-studded beaches, perfect for snorkeling and working on your tan. Meanwhile, a more lively experience can be had diving into the intricate underwater honeycomb of Widowmaker's Cave or by hitting the clubs and bars of the city's famous Hip Strip.

7. Fly from Fort Lauderdale to Cancun for as low as $203 round trip

This may be starting to feel a little unfair, especially as Fort Lauderdale is already replete with some of Florida's finest beaches and most luxurious resorts. But on top of San Juan and Montego Bay, its residents also have the choice of jetting off for a weekend to the Caribbean sands of Cancun for only $203 round trip. There, alongside a sun-kissed shoreline and a turquoise sea, they can enjoy fine dining and wild nightlife beside the waters of a tropical lagoon and visit evocative Mayan ruins at Chichen Itza.

6. Fly from New York City (LGA) to Toronto (YYZ) for as low as $199 round trip

Swap the streets of New York City for the great cultural melting pot of Toronto, Canada's biggest city. There's a huge amount to make the trip worthwhile, so if New Yorkers decide to hop the border for a quick peak, they'll need to do some sharp prioritizing. A prettily restored waterfront looks out over the vast blue expanse of Lake Ontario, while bike routes wind out of the city center along the wooded shoreline. Downtown hosts a huge variety of cuisines and drinking holes, while the city's diversity of excellent museums is unmatched elsewhere in Canada. WestJet run the cheapest route, which is direct and involves a travel time of just 90 minutes.

5. Fly from Newark to Toronto (YYZ) for as low as $199 round trip

Alternatively, a marginally cheaper route between New York City and Toronto flies from nearby Newark. United run the route in question, whizzing passengers north to Canada's Great Lakes region in just over 90 minutes. Flights are more expensive in summer and New Yorkers will likely only find the cheapest deals during spring, autumn or winter; the first two are glorious, colorful and verdant seasons in which to visit Toronto, but travelers might want to resist the temptation during winter, when temperatures plunge and the city's uglier, congested and overcrowded side swings into view.

4. Fly from Newark to Toronto (YTZ) for as low as $198 round trip

Connections between Newark and Toronto are so stupendously competitive that two of the top five cheapest international flights out of the United States are operated by carriers on this route. The cheapest of the two — at least on average, as airfares could of course vary on specific dates — are run by Air Canada, whose direct flights take 95 minutes to touch down in Toronto.

3. Fly from Los Angeles to Vancouver for as low as $198 round trip

At number three is a three-hour route that will take you from the Californian sun of Los Angeles to the temperate rainforests of Vancouver, cradled between the Coast mountains and the Pacific Ocean on Canada's western coast. This is a wonderful opportunity for LA residents to discover a North American city that could hardly be more different from their own. Vancouver's outdoor highlight is Stanley Park, where the beaches may not be as glamorous as those in California, but which boast spectacular views and plenty of great cafes in which to warm up after a chilly shoreline stroll.

2. Fly from San Diego to San Jose del Cabo for as low as $180 round trip

For as little as $180, San Diego residents can leave their own little patch of sunshine on the SoCal coast for a touch of Mexican magic in the quiet coastal town of San Jose. Situated on the very southern tip of the Baja California peninsula, which stretches its long limb out into the deep blue Pacific, San Jose is a peaceful beach town ideal for a quiet escape from San Diego's big-city life. Spirit run stupendously cheap flights, which are direct and take just two hours to cover the length of the Baja Peninsula.

1. Fly from New York City (JFK) to Toronto (YYZ) for as low as $154 round trip

Finally, the cheapest flights you can find beyond the borders of the United States go to Toronto, from New York City's JFK Airport. These flights are direct with a travel time of just under two hours, and somewhat surprisingly they aren't operated by any North American carrier but by TAM, the largest airline in Brazil. Clearly, broke New Yorkers won't have any problems getting to Toronto, with four different routes there included in the top 10 cheapest ways to fly out of the United States. And with Toronto's pretty lakeside setting, array of marvelous museums, and superb dining and drinking scenes, there are plenty of reasons to take advantage of this selection of cheap flights across the Canadian border.
