Open Jaw Flights: Save Time & Money on Multi-City Trips

You have client meetings in Chicago on Monday, a prospect dinner in Milwaukee on Wednesday, and a flight home to New York to catch. Booking two separate one-way tickets often costs more than a round-trip, but a standard round-trip forces you back to Chicago just to fly home. That's a wasted half-day you could spend selling.

Open jaw flights solve this. This guide walks through 5 parts: what open jaw flights are, four business-trip scenarios where they make sense, how to book them, the loyalty traps to avoid, and the risks to plan around. The payoff is simple: less unnecessary travel, fewer wasted hours, and a cleaner way to book multi-city work trips.

What Is an Open Jaw Flight and Why Does It Cost Less?

An open jaw flight is a round-trip ticket where your departure city and return city don't match. You fly into one city, travel between destinations on the ground, and fly home from a different city. The "jaw" is the gap you fill yourself with a train, rental car, or rideshare.

The key distinction: open jaw tickets are not two separate one-way tickets. They're booked through the multi-city search on airline or flight search sites and priced under round-trip fare logic. That means you can keep round-trip pricing while routing through multiple destinations, often paying less than two one-ways while skipping the repositioning flight entirely. Beyond airfare, you also avoid paying for ground transport back to your arrival city just to board a return flight.

When Do Open Jaw Flights Make Sense for Business Travel?

This routing wins when your meetings move through cities in one direction and doubling back mid-trip would waste time or money. If you're planning a more complex work trip, this fits naturally with broader trip planning and a tighter itinerary template. Here are the scenarios where it pays off most.

Sequential Client Visits Across Multiple Cities

Fly Chicago to Boston for Monday meetings, take Amtrak south through New York to Philadelphia for Thursday meetings, then fly Philadelphia to Chicago. No dead leg back to Boston, which would burn 4-5 hours on a flight you don't need. This approach works best when your ground segment is part of the multi-leg trip you needed to make anyway.

Conference Plus Client Meetings in Different Cities

Fly Austin to San Francisco for a conference, then continue to New York for office meetings and fly home from JFK. One split-city itinerary, round-trip pricing, and no backtrack flight to SFO. Skipping that return saves you roughly half a travel day you can spend prepping for the New York meetings instead.

Northeast Corridor and Short-Haul Routes

For city pairs like Boston to New York or Chicago to Milwaukee, Amtrak or a short drive often beats a connecting flight on total door-to-door time. Fly into one end, work your way through meetings along the corridor, and fly home from the other end.

When to Skip It

Stick with a round-trip if your trip naturally circles back to where you started, the gap cities have poor ground transportation, your schedule has no room for delays, or the ground transport cost exceeds the airfare savings.

How to Book Open Jaw Flights Step by Step

Every major booking site supports open jaw through the multi-city search option. The steps are nearly the same everywhere, and the same habits that speed up multi-city booking also help here.

• Google Flights: Click the trip type dropdown, select "Multi-city," enter your segments with dates, and click Search. Use metro area codes like CHI to compare nearby airports at once. Multi-city searches usually require specific dates instead of flexible calendar browsing.
• Airline websites: United, American, and Delta all have multi-city search options on their booking pages. Booking direct gives you a single point of contact for rebooking if something goes wrong.
• OTAs: Select multi-city instead of round-trip or one-way, and additional destination fields appear automatically.

Before committing, search a standard round-trip for the same dates so you know what the baseline price looks like. Then test both route directions for the open jaw, since direction can change the fare. For international trips, booking earlier usually gives you more options, but timing varies by route and season, so treat any "best window" advice as a guideline rather than a guarantee.

Planning multi-destination routing manually across multiple sites eats time you could spend on client prep. If you want one place to review trip options, Otto the Agent curates 2-6 top flight options for multi-city trips in one interface, so you can compare strong choices without repeating the same search across multiple sites.

Fare Class and Loyalty Program Traps to Avoid

Open jaw tickets earn miles and status credits segment by segment, just like any other ticket. The routing itself doesn't help or hurt your earning. But fare class can quietly destroy your status progress, which is why it helps to understand basic loyalty tracking before you book.

Basic Economy is the main trap. On some major U.S. carriers, that fare strips out flexibility, can reduce what you earn toward status, and may not work for certain multi-city or open jaw itineraries at all. American Airlines, for example, blocks domestic open jaw and multi-city itineraries on Basic Economy fares entirely, and as of December 17, 2025, Basic Economy tickets on American no longer earn AAdvantage miles or Loyalty Points. Award travel is another watch-out: some programs price open jaw awards as two separate one-ways instead of giving you any round-trip discount.

The takeaway: book Main Cabin or higher for any open jaw itinerary. That matters even more if you're trying to protect status progress on a trip with multiple moving parts.

Risks Worth Planning Around Multi-City Flight Bookings

Open jaw flights carry real downsides that go beyond typical booking risk. Your air and ground segments are partly separate, so one delay can ripple through the rest of the trip.

• Disruption exposure on the gap segment: If your inbound flight is delayed and you miss your Amtrak between cities, the airline rebooks your flight but the train is your problem. Build a meaningful buffer between your scheduled flight arrival and ground departure, especially if the meeting is high stakes.
• Baggage handling: You claim checked bags at your first destination and physically haul them through the ground segment yourself. For short business trips, go carry-on only.
• Expense report friction: An open jaw trip splits into airfare plus ground transport, which may fall under different approval thresholds. Label it clearly as "Multi-city / Open Jaw" on your expense report and include a quick cost comparison against a standard round-trip to justify the split booking. If that process is already messy, tighten it up with an expense management plan or a strategy for avoiding report rejections.
• Hidden ground costs: Run the full cost equation before booking: the airfare savings minus ground transport and time costs. If the math doesn't work, book a round-trip.

If things go wrong, remember what the airline actually owes you. DOT aviation consumer protections apply to your air segments, but not to the train, rental car, or rideshare you booked to bridge the gap.

Turn This Routing Into a Booking Advantage

Open jaw booking works best when your meetings move in one direction and your travel should do the same. Once you stop forcing a round-trip shape onto a multi-city schedule, you protect work time and often avoid paying for travel you didn't need.

The hard part is locking down the flight segments fast enough to plan your ground connections around them. Otto makes this easier by letting you pick arrival and departure times that leave enough room for your trains, drives, or rideshares between cities.

FAQ

Are Open Jaw Flights Cheaper Than Round-Trip Tickets?

Sometimes cheaper, sometimes similar, but the biggest win is usually avoiding the added time and cost of repositioning back to your arrival city. Always factor in the ground transport cost for the gap segment when comparing total trip price.

Can You Book These Flights on Basic Economy Fares?

Not safely. Some carriers block multi-city itineraries on Basic Economy entirely, and others limit changes if your schedule shifts mid-trip. See the Fare Class section above for carrier-specific details.

What Happens If Your Flight Is Delayed and You Miss a Ground Connection?

The airline covers your air segment under its normal rebooking rules, but any independently booked ground transport is on you. Federal traveler protections don't extend to self-booked trains, rental cars, or rideshares, so budget extra buffer time between your landing and your next departure.

How Do You Handle These Trips on Expense Reports?

Show the full routing and break it into two line items: airfare and ground transport. Including a quick cost comparison against a standard round-trip with repositioning helps justify the split booking if your finance team asks.

How Can You Quickly Compare Multi-City Flight Options Without Checking Multiple Sites?

Google Flights' multi-city search is the fastest free starting point. If you want curated results matched to your schedule instead of raw search output, Otto shows 2-6 strong options in one view so you spend less time filtering and more time deciding.
