Top tips for finding a cheap flight to Baltimore/Washington International Thurgood Marshall Airport (BWI)

Book in the Goldilocks Window

The period of time when you have the best chance of finding cheap flights is what we call the Goldilocks Window because it’s not too far in advance but not too last minute either—it’s just right. To avoid the predictable 21-, 14-, and 7-day price hikes, that window is in the 1-3 month period before a domestic flight and the 2-8 month period before an international one.

If your travel falls during peak season—the summer months or around the winter holidays—the ideal time to book shifts a bit. You’ll usually find the best summer vacation deals in December or January, while the cheapest winter flights are often available around June or July.

Use the Greek Islands Trick

While we devised this trick to get you across the ocean as cheaply as possible it can also be used in the US as well. The gist of it is: focus on getting close to where you want to go rather than all the way there, and you could save quite a bit of money. For Baltimore, this means looking into other DC airports or even as far as Philly or Richmond. For example, if a flight from SFO to Baltimore is $500 and a flight to Philadelphia is just $300, that few hours in the car would be worth the savings.

There’s a little extra planning involved in this strategy and potentially some more travel time, but it’s a great way to get to faraway places for less. You’ll find it works especially well when trying to get to a small airport, flying on an unusual route, or visiting somewhere that’s isolated, like an island.

Search alternate departure airports

To score the best deals, check out flights to Baltimore from multiple departure airports near you. If you live in southern Florida, for example, look for flights to BWI from both Miami and Fort Lauderdale and compare prices. The savings can be so significant that they more than makeup for a long drive or the price of a connecting flight.

Fly when it’s cheap

If you’ve ever tried to fly around the winter holidays or during the summer months, you know airports are busy then. Both are considered peak travel seasons, when airlines have an excuse to raise prices. That means to find low fares, you may have to fly when it’s cheap, like shoulder seasons or take an international trip around Thanksgiving when most travelers are looking for domestic flights.

Sometimes you don’t have as much wiggle room with the dates you fly, but that doesn’t mean accepting sky-high fares. You can try to book flights at the very beginning or very end of the summer rather than smack dab in the middle, or look for trips that depart on Tuesdays, Wednesdays, and Saturdays rather than Fridays or Sundays.

Set alerts for specific trips

Our last piece of advice is to set alerts for specific trips. As you go about your flight research, sign up for email alerts for the trips you want to take and wait for email notifications when prices drop. To give yourself the best chance of scoring a deal, set these alerts several months before your trip, like even before the Goldilocks Window mentioned above.

There are 20 different airlines that fly out of BWI, operating more than 650 flights a day to destinations both domestic and international. That means you have plenty of routes to choose from!
