Research Briefs
Iberia Travel Research Briefs
Source-backed analysis on Spain and Portugal routes, train-vs-flight decisions, travel time, cost, carbon impact, and route friction.
Independent research. Transparent assumptions. Human-verified data.
Odyssey Discoveries Research Briefs are practical, data-driven travel analyses focused on Spain and Portugal. Each brief examines real route decisions using transparent assumptions around door-to-door time, cost, carbon impact, reliability, and travel friction.
These briefs are designed for travelers who want more than inspiration — they want evidence before choosing whether to take the train, fly, use a bus, or rethink the route.

Methodology
How Odyssey Discoveries Research Briefs Are Built
Each research brief uses a transparent decision framework. We compare routes using door-to-door time, access penalties, estimated cost ranges, emissions assumptions, reliability factors, and practical traveler friction. When data is uncertain, assumptions are stated clearly rather than hidden.
