Connecting flights from London Heathrow Airport (LHR) can sometimes provide cheaper economy fares than direct services due to competition at hub airports, but they increase travel time and risk of missed connections. Popular connecting hubs for budget-friendly itineraries include Madrid, Lisbon, Dublin and various European low-cost hubs; for long-haul savings, connections via Reykjavik or major Gulf hubs can be economical. If travel time and convenience are priorities, direct flights may be worth the premium; for the lowest landed cost, compare multi-leg itineraries while factoring in baggage, transit visas and connection buffers.
