Quick summary
A Warsaw connection is not automatically cheaper than a Turkish Airlines nonstop to Istanbul. A peer-reviewed study in Transport Policy in July 2026 found U.S. legacy carriers often kept connecting itineraries above a rival’s nonstop fare in that rival’s hub market — a pattern called respect pricing. No comparable fares for either routing could be confirmed as of 14 October 2026.
The study’s evidence is U.S. domestic, so it describes how connecting fares get set, not this corridor’s prices. Below: what the finding changes, and the one Warsaw departure the airline itself confirms.
No airline, airport or government source in this update prices a Warsaw connection and a Turkish nonstop against each other on the same city pair. The fare figures that once appeared here are therefore no longer published. For a North America–Turkey trip priced in October 2026, the comparison is a task, not a conclusion. A stop does not make an itinerary the discounted product by default.
That changes the assumption behind this page. Most travelers routing to Istanbul through Warsaw bet that a one-stop itinerary costs less than the nonstop on the same city pair. In the U.S. domestic market, where researchers have the cleanest data on how airlines price connections, that bet often loses.
The price itself remains open.
Why a connection is not automatically cheaper
Legacy carriers routinely kept connecting itineraries above a rival’s nonstop fare in that rival’s hub market, according to a peer-reviewed study in Transport Policy published in July 2026. The study examined U.S. domestic markets. The effect strengthened as more legacy carriers served the hub market. It weakened — without disappearing — where Southwest operated.
The pattern is called respect pricing. On the pairs the study measures, the carrier selling the connection had no rival on that city pair, while the nonstop did. The connecting seller faced no competitor pressing its fare down.
The finding cannot settle which of those conditions describes a Warsaw–Istanbul itinerary. The data cover domestic markets, not international ones, so the result explains how connecting fares get set rather than establishing this corridor’s prices.
The dynamic has surfaced elsewhere in this market, as on the Japan route where a layover stopped beating the nonstop. Warsaw’s gateway pricing also has its own record against Western European hubs on another long-haul corridor.

What the airline itself confirms about Warsaw
LOT Polish Airlines’ own press office confirms one addition to its North American network: Warsaw–San Francisco, four weekly Boeing 787 flights, launched on 6 May 2026, according to the airline’s launch announcement. It is the one North America–Poland frequency in this update that comes from the airline rather than from a fare table.
That is a schedule, not a daily service. For a Bay Area traveler, the trip is planned around departure days rather than a preferred time of day. The outbound leg of a Warsaw itinerary can begin on the Polish carrier’s own metal from San Francisco.
As of 14 October 2026, the route is part of the carrier’s operating transatlantic schedule, not a pending announcement. The airline publishes its days and frequencies, which can be adjusted with the season.
How to judge the two itineraries
The comparison turns on competition, not the number of stops. In the U.S. data, the event associated with changed pricing was a carrier starting to fly the nonstop. The study’s wider literature also shows how quickly a low fare can follow a competitor out of a market.
The distinction is between a price and the pressure behind it.
Where that pressure is absent, the carrier selling the connection sets its price without it. A historical case shows how a competitor’s arrival and departure can change the fare on the same route.
What the pricing pattern means for your trip
The two itineraries need a same-date comparison. The connecting fare is the one to verify, not the nonstop.
Comparing a connection with a nonstop. Price both as single tickets for the same dates, and treat a connection that comes back higher as the expected result rather than a mistake in your search. Watch route announcements rather than discounts, especially for a budget carrier announcing the nonstop on your pair: that is the condition the study associates with narrower gaps. If a low-cost carrier puts a nonstop on your city pair, re-run the comparison from scratch. Less suited: travelers whose city pair already has a low-cost nonstop, where the study found the effect weaker.
Departing from the US West Coast. Match your travel dates to one of the four departure days before building anything onward from Warsaw. Watch the airline’s published schedule for seasonal adjustments. Less suited: travelers whose dates fall on the three days a week the San Francisco flight does not operate.

Questions? Answers.
Is a Warsaw connection cheaper than a Turkish Airlines nonstop to Istanbul?
No comparable fares for the two routings could be confirmed from an airline, airport or government source as of 14 October 2026, so it is unproven either way. What is documented is that a connection is not automatically the cheaper product: a July 2026 study in Transport Policy found connecting itineraries held above rival nonstops in rival hub markets.
Does LOT still fly the North American routes this page used to list?
The airline’s own press office confirms Warsaw–San Francisco: four weekly Boeing 787 flights that launched on 6 May 2026. Other North American frequencies previously listed on this page are not supported by an airline, airport or government source and have been removed.
Why would a connecting itinerary cost more than a nonstop?
The July 2026 Transport Policy study found the pattern strengthened as more legacy carriers served the hub market and weakened, without disappearing, where Southwest operated. The authors call it respect pricing: the carrier selling the connection faces no rival on that city pair, so nothing presses its fare down.
Could the price gap close again?
The U.S. data point to one trigger: a low-cost carrier operating the nonstop into the hub. Where Southwest flew, respect pricing weakened. A sale or a limited-time discount is a different mechanism from the one the study measures, and the research does not cover it.
