Why Fintechs Choose RunRelay

Embedded travel that actually works

Most travel APIs give you search results and leave you to figure out the rest. RunRelay handles everything: search, booking, payment, ticketing, changes, cancellations, and customer support — end to end.

⚡

One API, Full Execution

Send a travel intent, get a confirmed booking. RunRelay isn't a search engine — it's an execution engine. Flights, hotels, insurance, and ancillaries are handled through a single REST endpoint. No need to manage multiple supplier integrations or booking flows yourself.

✈️

LCC Coverage Nobody Else Has

Ryanair. Wizz Air. EasyJet. The carriers your users actually fly — but that no GDS or NDC aggregator covers. RunRelay provides real-time search and booking for low-cost carriers through proprietary integrations, giving your fintech app inventory that competitors simply can't match.

💳

Wallet & Billing Integration

Charge directly to your user's wallet, prepaid card, or connected payment method. RunRelay supports flexible billing models — pass-through pricing, markup, or commission-based. Multi-currency settlement in 50+ currencies with detailed reconciliation reports.

🔔

Webhook Callbacks

Every booking event triggers a webhook: confirmation, ticketing, schedule changes, cancellations, and disruption alerts. Build reactive workflows in your app without polling. Ideal for async architectures and event-driven fintech platforms.

🤖

MCP Compatible

Beyond REST, RunRelay supports the Model Context Protocol (MCP) — making it instantly compatible with AI-powered features in your fintech app. Let your AI assistant search and book travel through the same execution layer your app uses.

🛡️

Concierge Fallback

When automation hits an edge case — a name change, a complex multi-city itinerary, a visa question — RunRelay's 24/7 human concierge takes over. Your users get resolution without your support team lifting a finger.

Integration

Ship travel in your fintech app — without building a travel company.

RunRelay is designed for engineering teams that want to add travel as a feature without the 12-month integration cycle. Our API is opinionated: send intent, get results, confirm booking. Three calls maximum for a complete round-trip.

// Search flights — including LCCs
const results = await relay.searchFlights({
  from: 'BER',
  to: 'BCN',
  date: '2026-04-10',
  passengers: 2,
  include_lcc: true  // Ryanair, Wizz, EasyJet
});

// Book the cheapest option
const booking = await relay.book({
  offer_id: results.offers[0].id,
  passengers: [{
    first_name: 'Alex',
    last_name: 'Chen',
    email: 'alex@example.com'
  }],
  payment: {
    method: 'wallet',
    wallet_id: 'wal_8k2mN'
  }
});

// Webhook fires on confirmation
// → booking.confirmed { pnr: "ABC123" }
LCC Advantage

The carriers your users fly — that nobody else covers.

Low-cost carriers account for over 30% of European air traffic, yet they're absent from virtually every travel API. GDS systems don't support them. NDC aggregators skip them. Your users end up booking on airline websites — outside your app, outside your revenue.

RunRelay maintains proprietary integrations with Ryanair, Wizz Air, EasyJet, and other major LCCs. Real-time availability, seat selection, baggage add-ons, and booking — all through the same API you use for full-service carriers.

Travel as a Service

Revenue model that works for fintechs.

RunRelay isn't just infrastructure — it's a revenue stream. Choose the model that fits your business:

  • Markup model — add your margin on top of net fares
  • Commission model — earn per booking, no upfront cost
  • Subscription model — bundle travel into your premium tier
  • White-label — full branded experience under your domain
  • Hybrid — combine wallet top-up with travel rewards
