What TripStack does
TripStack is a B2B travel technology company that builds Virtual Interlining (VI) infrastructure, combining flights from multiple non-cooperating carriers (low-cost carriers, full-service carriers, and NDC-enabled airlines) into single, retail-ready itineraries. Founded in Toronto in 2016 and acquired by Sweden-based Etraveli Group in 2019, TripStack operates a multi-cloud (GCP and AWS) flight booking API that exposes 100+ LCCs, a growing roster of FSC NDC integrations (IATA NDC 17.2 certified), and TripStack-built VI fares; the platform processes 240M+ daily API searches across 40B+ daily price points and serves 28,000+ daily bookings, 16M+ annual passengers, and $3.1B USD of annual gross sales.
Its three core product lines are the TripStack API (the central flight content endpoint for OTAs and travel retailers), Self-Connect for Airlines (a customisable white-label platform that lets airlines retail VI fares on their own websites, with TripStack acting as Merchant of Record and offering a Self-Connect Guarantee covering missed connections), and FareShare (a subscription-based LCC content caching module delivered via FTP). The underlying VI engine, supported by 200+ employees across offices in Toronto, Pune, and Kraków, applies flight-matching, pricing, and automated rebooking algorithms to assemble unique itineraries that are unavailable through traditional GDS or interline channels.
TripStack makes money through transaction-based booking fees as a percentage of fare on VI, LCC, and NDC content; a recurring FareShare subscription; revenue-share economics on airline whitelabel deployments; and Merchant of Record payment economics across 19 payment methods, 40 currencies, and 10 payment providers. Its customer base spans airlines (Azul, Nok Air, Etraveli-owned carriers, plus 20+ NDC partners), OTAs and travel retailers (Alternative Airlines, eSky, SmartFares, LBF Travel, Tryp.com, Travelyn), airports (Aeroporti di Roma), and technology partners (Navitaire, Amadeus, InteliSys, Etraveli Group), with strategic distribution amplified through Etraveli's consumer brands and Amadeus/Navitaire-hosted carrier networks.

Product overview
TripStack is a B2B Flights-as-a-Service platform built around three named offerings that share a common Virtual Interlining (VI) technology core. The TripStack API is the central flight booking product, exposing 100+ LCC integrations, Full-Service-Carrier NDC API integrations, and TripStack-built Virtual Interlining fares through a single endpoint with self-serve onboarding. The Self-Connect for Airlines product is an add-on White-Label platform that lets airlines retail VI / Self-Transfer fares from their own websites with TripStack acting as Merchant of Record and providing a Self-Connect Guarantee. FareShare is an add-on LCC caching module that supplies cached low-cost-carrier price points and itineraries to lower Look-to-Book ratios and power pricing calendars. Underlying all three is TripStack's proprietary Virtual Interlining technology — the flight-matching, pricing and automated rebooking engine — and the company also operates as Etraveli Group's Flights-as-a-Service gateway, exposing the parent group's flight content, payments, fraud prevention, pricing, and customer support to OTAs, airlines and meta platforms.

Company assessmentDirect peers
- Dohop: Dohop is a Reykjavik-based Virtual Interlining and self-connect technology provider founded in 2004, directly competing with TripStack by combining non-cooperating carriers into single itineraries for airlines, OTAs, and airports. The closest direct peer in the VI/self-connect space.
- Duffel: Duffel is a London-based flight booking API for travel businesses, providing access to NDC and LCC content. Direct peer to TripStack's API product, serving OTAs and travel retailers with aggregated flight content via a developer-facing API.

Emerging players

- Hopper: Hopper is a mobile-first OTA and travel fintech that has explored self-connect and Virtual Interline offerings through partnerships. Emerging player with partial overlap in the VI product category, primarily consumer-facing rather than B2B infrastructure.
- Self-Transfer.com: Self-Transfer.com is a smaller specialist offering self-connect itineraries to consumers. Niche emerging player in the VI/self-connect category with meaningful but smaller-scale product overlap with TripStack's Virtual Interlining technology.
Broad incumbents
- Amadeus: Amadeus is the world's largest GDS and travel technology incumbent, offering NDC aggregation and the Amadeus Travel Platform with which TripStack has a strategic content partnership. Broad incumbent competing in airline distribution and NDC content aggregation.
- Sabre: Sabre is a leading global GDS and travel technology incumbent offering NDC content aggregation via SabreMosaic and a broad portfolio of airline and travel-retailer solutions. Broad incumbent competing with TripStack's NDC aggregation capabilities.
- Travelport: Travelport (now part of the Kiwi.com/Etraveli-adjacent ownership chain) is a major global GDS offering NDC content distribution and is itself the parent of Kiwi.com. Broad incumbent and indirect connection given its positioning in flight content distribution.
