Cheap flights from Glasgow to London

October is the cheapest month on this route, sitting after the summer rush and before the winter holidays. Fares climb through summer and again around Christmas and New Year, when travel between Scotland and England peaks. Midweek departures, especially Tuesday and Wednesday, usually undercut Friday evenings and Sunday nights, which weekenders fill first. Book a few weeks ahead in the quiet months, and earlier if your dates fall in a school break or a holiday week.

Ryanair UK and Easyjet cover the low-cost end of this route, with fares that leave out a checked bag and seat choice unless you add them. British Airways and BA CityFlyer fly full-service, so a cabin bag and a drink come with the ticket. Loganair Limited, Aer Lingus and Emerald Airlines link Scotland and Ireland with onward legs toward London, while KLM Cityhopper, Air France and Edelweiss Air turn up on connecting itineraries rather than direct hops. Whatever you pick, read what the fare includes before you compare totals.

London has five airports and they are not interchangeable. London City sits closest to the centre, with the Docklands Light Railway and the Tube running into the City and the West End. Heathrow lies west of town, served by the Piccadilly line, the Elizabeth line and express trains to Paddington. Gatwick is south, with trains into Victoria and London Bridge, while Luton and Stansted sit further out and lean on trains and coaches to reach the middle of the city. Allow real time for the transfer and check which side of London your onward plans start from.
