Three friends in Boston, Austin and Seattle have around 55 destinations served nonstop from all three home airports, according to Midway’s route data for the next twelve months. Minneapolis is the Midway Point for that trio (the shared destination Midway marks as the fairest by distance), and each of the three flights there takes between about 2h45 and 3h30. The same two steps work for any three cities: list what all three airports reach nonstop (no change of plane), then look at how the flying time splits.
This page works through five trios, in the US, Europe, Asia-Pacific, Latin America and across three continents. The figures come from Midway’s route data as of October 2026, which covers the next twelve months of schedules for the 600 busiest airports. Each example uses one airport per city (Stockholm Arlanda, São Paulo Guarulhos, Toronto Pearson and London Heathrow where a city has several), and the counts are rounded to the nearest 5. A destination counts as shared if all three airports have a nonstop to it in at least one month, so a few on each list are seasonal.

How a third city shrinks the list
Each pair in the US example shares a similar number of destinations, and the third city removes about a quarter of them. In the Asia-Pacific example the drop is steeper. Singapore and Hong Kong share around 110 destinations as a pair, and adding Sydney leaves around 45 served nonstop from all three. Sydney’s network is the smallest of the three, so it sets the ceiling.
The thinnest pair matters more than the third city. Toronto and Mumbai share around 25 destinations as a pair. Adding London still leaves around 20 served nonstop from all three, because almost everything Toronto and Mumbai share is already on London’s map. Before adding names to a search, it is worth checking which two cities have the least in common.
Choosing between the shared destinations
Once the list exists, two things narrow it. The first is how the flying time splits. Midway’s “Let’s meet midway” button marks one destination as the Midway Point. It scores each shared destination by the average distance from the home cities plus one and a half times the largest gap between any one city’s distance and that average, and picks the lowest score. The extra weight on the largest gap is deliberate: it penalises a destination where one person flies much further than the other two. The score uses distance, not flight time, and it knows nothing about fares, visas or time off.
The second is the month. A destination on the yearly list may only be served by all three airports in some months, and the month filter in Midway shrinks the list to the destinations with nonstops from every home city in the month you pick. The general version of this method, for any number of cities, is in the guide to finding a common destination from multiple cities.
Boston, Austin and Seattle
Each pair of these cities shares between around 70 and 75 destinations, and around 55 are served nonstop from all three. Minneapolis is the Midway Point. The flights there take about 3h20 to 3h30 from Boston, 2h45 from Austin and 3h20 from Seattle, all year.
Chicago O’Hare splits less evenly: about 3h05 to 3h20 from Boston, 2h50 to 3h05 from Austin and just over 4 hours from Seattle. Denver, the usual suggestion for a coast-to-coast group, leans West here. Austin and Seattle are about 2h35 to 3h away, while Boston is about 4h30 to 4h50. The list also has an option abroad: London Heathrow, about 6h50 from Boston and between 9h10 and 9h40 from Austin and Seattle.
Stockholm, Lisbon and Athens
These are three corners of Europe, and they have around 70 destinations served nonstop from all three. Stockholm Arlanda and Athens share around 100 as a pair. Milan Malpensa is the Midway Point, and it is close to even by flight time as well: about 2h45 from Stockholm, 2h35 to 2h45 from Lisbon and 2h35 from Athens. Zurich is similar, at about 2h30, 2h55 and 2h50, and both run all year from all three cities.
Several Italian options are seasonal. Pisa has nonstops from all three cities only in June, July and August, and Bologna and Venice are mostly summer routes for this trio. For an autumn or winter trip, filter by month before choosing. The most connected cities in Europe guide covers the wider European network.
Sydney, Singapore and Hong Kong
Around 45 destinations are served nonstop from all three, and Sydney’s leg is the long one to every Asian city on the list. Denpasar (Bali) is the Midway Point, at about 5h35 to 6h35 from Sydney depending on the month, 2h35 from Singapore and 5h05 from Hong Kong. Perth is another option, at about 5 hours from Sydney, 5h05 to 5h25 from Singapore and 7h35 from Hong Kong.
The rest of the list is mostly East and Southeast Asia, where Singapore and Hong Kong have short flights and Sydney has eight to twelve hours for most cities. The most connected cities in Asia-Pacific guide ranks the region’s hubs by the same route data.
Mexico City, Bogotá and São Paulo
This trio has around 20 destinations served nonstop from all three. Lima is the Midway Point: about 6 hours from Mexico City, 3h10 from Bogotá and 5 hours from São Paulo. Panama City is closer for two of the three, at 3h50 from Mexico City and 1h45 from Bogotá, but about 7 hours from São Paulo.
The destinations where the three flight times are closest to each other are in Europe. Madrid is about 10h35 to 11h05 from Mexico City, 9h30 from Bogotá and 10h05 to 10h20 from São Paulo, and Barcelona, Paris, London and Frankfurt are in the same range. That evens out the flying, but it costs each person a long-haul flight, where Lima keeps everyone at about six hours or less.

Toronto, London and Mumbai
With three continents involved, around 20 destinations are served nonstop from all three. Athens is the Midway Point: about 9h30 from Toronto, 3h35 from London and 7h10 to 7h35 from Mumbai, though the Toronto flight does not run in February. Istanbul runs all year from all three cities, at about 9h50 to 10h05 from Toronto, 3h55 from London and 7h20 to 9h10 from Mumbai.
Rome is on the yearly list but has nonstops from all three cities only from October to December 2026. Cairo is also on the list, at about 10h25 from Toronto, 5h05 from London and 6 to 6h35 from Mumbai. For more on groups split between continents, see the intercontinental meeting points guide.

After the shortlist
The shared list and the Midway Point settle the flights. They do not settle the dates, the budget or who has the least time off, and in a group of three those usually decide between the two or three cities that work on flights. The group trip planning guide covers the vote and the booking.
