Duffel + Logostream
The Complete Booking UI Stack
Duffel powers your flight search and booking. Logostream powers the visual layer — 1,100+ airline logos, airport logos, aircraft liveries, and route maps. Together, a complete aviation product.
What Is Logostream?
Logostream is the visual and branding layer for aviation booking UIs. It provides airline logos, airport logos, aircraft liveries, and route map images through a single REST API key — purpose-built to complement booking engines like Duffel with the complete visual experience.
Common use cases alongside Duffel include:
- Airline logos on search results, including null fallbacks for Duffel's limited coverage
- Airport logos for origin and destination display
- Aircraft livery images on booking confirmation screens
- White and dark logo variants for flexible UI designs
- Embeddable route maps on itinerary and confirmation pages
Logostream is the visual/branding layer — purpose-built to complement flight booking engines. Free tier, HTTPS, transparent pricing, and self-serve signup in seconds.
What Is Duffel?
Duffel is a B2B travel booking API that provides access to airline inventory (NDC + GDS), hotel stays, and ancillaries through a unified REST API. It is priced at $3.00 per confirmed flight order, with free sandbox/test mode.
Its core offering includes:
- Flight search across NDC and GDS airline inventory
- Booking, seat selection, and baggage ancillaries
- Hotel and stays booking through a unified API
- Airline logos for ~300 airlines in its booking network (can return null)
- $3.00 per confirmed flight order; free sandbox/test mode
Duffel does return airline logos for airlines in its booking network — but coverage is limited to approximately 300 airlines, the field can return null, SVGs are light-background only (no dark or white variants), and there are no airport logos or aircraft liveries. Duffel is the booking engine layer; Logostream is the visual/branding layer — they are complementary, not competing.
Feature Comparison
Logostream and Duffel — two complementary APIs, different capabilities.
Why Duffel developers add Logostream
Four reasons Logostream completes the Duffel booking experience.
Duffel's logo coverage is incomplete
Duffel returns airline logos for ~300 airlines in its booking network. Logostream covers 1,100+ airlines — and the logo field can return null in Duffel's API. Logostream is the reliable fallback and expansion.
Airport logos are missing entirely
Duffel has no airport logo assets. If your booking UI shows departure and arrival airports (it should), you need Logostream. 600+ airport logos, same endpoint pattern.
More logo variants than Duffel can provide
Duffel only serves light-background SVGs. Logostream adds white, dark, PNG, JPG, and transparent variants — essential for flexible booking UI designs on any background.
Route maps and liveries complete the experience
Show customers the actual aircraft livery and a visual route map on the booking confirmation. Neither is available from Duffel. Logostream delivers both from a single API key.
Final Verdict
The honest take — Duffel + Logostream is the complete booking stack.
Use Logostream + Duffel together if…
- You want a complete booking UI with a full visual layer
- You need reliable airline logos beyond Duffel's ~300 airline coverage
- You need airport logos on departure and arrival display
- You need dark or white logo variants for flexible UI designs
- You want route maps and aircraft liveries on confirmations
- You want to handle Duffel's null logo field gracefully
Use Duffel alone if…
- Building an MVP or prototype with minimal visual requirements
- Backend booking engine with no user-facing interface
- Demo or proof-of-concept where text-only airline names are acceptable
- You only need airlines within Duffel's booking network with SVG logos
What developers say
Duffel developers who added Logostream to their stack.
"Duffel's airline logo field returns null for a surprising number of airlines. Logostream is our guaranteed fallback — and primary source for the 800+ airlines Duffel doesn't cover."
"Airport logos aren't in Duffel at all. Every airport on a search result now has a logo, thanks to Logostream. Took 30 minutes to integrate."
"White logo variants on our dark booking confirmation page — Duffel's SVGs don't work on dark backgrounds. Logostream solved this with a single query parameter."
"The aircraft livery on the booking confirmation is something our users comment on. Duffel tells us the aircraft type. Logostream shows us what it looks like."
"We use Duffel for booking and Logostream for everything visual. The combination is the complete aviation API stack — I'd recommend it to every Duffel developer."
"Route maps from Logostream + booking from Duffel + flight tracking from another provider. The modular aviation API stack is the way to build travel products."
