Internal flights & transport¶

Colombia has a dense domestic network (Avianca, LATAM Colombia, Wingo, JetSMART, SATENA, etc.).
Route for this trip, per the itinerary: Bogotá → Armenia/Pereira (coffee region) → Medellín → Cali (or Santa Marta/Tayrona/Cartagena if the coast alternative is chosen) → Bogotá → London.
Sample dates, one-way GBP fares, and Google Flights links for that spine live on Itinerary → Internal transfers (snapshot dated there; re-check before buying).
Book 2–3 internal flights about 2–4 weeks before travel for decent prices and convenient times.
Prefer morning flights where possible (less delay-prone).
Buses: buy locally; Colombia has extensive long-distance bus networks. Use mainly between regional hubs when flights are inconvenient (e.g. Medellín ↔ Bogotá is ~1h flight or ~9h bus; coffee region ↔ Medellín is often worth comparing bus vs short hop).
