Cheap flights from London to Southampton

October stands as the cheapest month on this route, making it a sensible time for budget-conscious travellers heading south from any of London's airports. School holidays, Christmas periods and summer vacations bring higher demand across all carriers operating between these two cities. Weekday departures typically cost less than weekend travel, especially when avoiding peak holiday windows throughout the year.

British Airways and BA CityFlyer provide full-service options with baggage and meals included in most fares. Accesrail operates ground connections rather than air services, offering an alternative for passengers preferring rail journeys. Aurigny Air Services, KLM Royal Dutch Airlines, Aer Lingus and Loganair Limited connect through their respective hubs at additional cost on separate tickets.

Southampton Airport sits roughly twenty miles from the city centre with regular bus and taxi services available throughout the day. Public transport connections run frequently during daytime hours, while evening flights may require pre-booked taxis or later bus schedules. Allow extra time for security queues during peak travel periods and check which terminal your carrier departs from before arriving.
