But, remember that London Gatwick is only one of the airports in London – searching for flights from ‘Belfast’ to ‘London’ will give you more options, and possibly lower prices.
You can expect prices to be at their highest in August. If you're looking for a budget break to United Kingdom and are flexible on dates, search for flights by month to find the best offers.
We don't just compare flight prices. If you need to book accommodation for your trip, or you want to hire a car to explore United Kingdom, we've got some options for you to compare. Plus, when you sort your flights and hotel in one booking, you could save even more.
