Cheap Flights from London to Iasi Starting at $33

London is served by several airports that together cover a range of travel needs. Heathrow is the city’s primary international hub, typically used by full-service carriers and long-haul flights; it sits about 15–20 miles west of central London, with the Heathrow Express taking roughly 15–20 minutes to Paddington (higher fares) while the Underground and buses are slower but cheaper. Gatwick often functions as a mix of international and low-cost services, around 25–30 miles south—the Gatwick Express reaches Victoria in about 30 minutes, while coaches and trains provide lower-cost, longer options. Stansted and Luton are usually budget-oriented bases serving many low-cost European routes; both are roughly 30–45 miles from central London, with express trains of 45–50 minutes or coaches lasting 60–90 minutes at lower fares. London City Airport is a compact, business-focused option close to Canary Wharf and the Docklands—only about 6 miles east of central London—with quick DLR and taxi connections in 20–30 minutes, often preferred for convenience despite a smaller route network. Pros include a wide range of flight choices across price points and multiple transport links; cons can be variable transfer times and extra costs for express services or longer coach journeys.

Iași International Airport (IAS) is the main gateway to Romania’s Moldavia region and typically functions as a regional international hub rather than a long-haul gateway. It usually hosts a mix of legacy and low-cost carriers offering seasonal and year-round routes across Europe, with fares that can be competitive on budget airlines and mid-range on traditional carriers. The airport lies about 8–10 km northeast of Iași city center; travel time is commonly 15–30 minutes by taxi or ride-hail, and around 25–40 minutes by public bus with fares generally low. Pros include compact terminals and straightforward transfers; cons can be limited late-night services and fewer long-haul connections compared with larger national hubs.
