London is served by several airports with distinct roles and travel profiles. Heathrow is the city’s primary international hub, typically handling long-haul, full-service carriers and premium traffic; it sits about 20–25 km west of central London and is usually accessed via the Heathrow Express (15–20 minutes, premium fare), the Elizabeth line or Piccadilly Line (30–60 minutes, cheaper), and taxis or private transfers. Gatwick functions as a large international and leisure gateway, commonly hosting both full-service and low-cost carriers about 45–50 km south; Gatwick Express trains to Victoria take roughly 30 minutes, with slower and cheaper rail options and coach links. Stansted and Luton are generally positioned as budget-focused airports north and north-east of the city, favored by low-cost airlines; coaches and trains to central London typically take 40–80 minutes with economy fares often lower than rail alternatives. London City Airport caters mainly to business travelers and regional routes, lying closest to the financial districts (about 10 km east) and offering quick docklands DLR or taxi connections in 20–30 minutes. Pros across the network include wide route choice and frequent services; cons can be travel time variability, peak congestion, and extra transfer complexity when choosing between airports.

Kaunas Airport (KUN) is Lithuania’s second-largest airport and typically serves as a budget-friendly alternative to Vilnius, often handling low-cost carriers alongside some charter services. It’s located about 15–20 km southwest of Kaunas city centre, with travel times usually around 20–35 minutes by car depending on traffic. Public transport options include regional buses and occasional shuttle services; fares can generally be modest, often in the low single-digit euros, while taxis or ride-hailing tend to be quicker but costlier. The airport is compact and easy to navigate, which can make connections convenient, though facilities and frequency of routes can be more limited compared with larger international hubs.

In different months, ticket prices from London to Kaunas vary: minimum — $27 (September 2026), maximum — $61 (August 2026). Typically, the flight costs $39–$90.
