Autumn foliage season in the Big Apple. Good weather, pretty trees, highly recommended.

The lowest fares (those listed below) start in late October but you'll find tonnes of options in September for around £10-£20 more, which is likely as low as we'll see for such a popular time to visit. Manchester doesn't have the same late summer deals, unfortunately. However, these Aer Lingus fares are quite good value in those months if you're taking a checked bag as it comes included in the fare.

1. Head to Google Flights and use their handy calendar tool to find the best travel dates for your route, by locating the dates with the lowest fares (those highlighted in green). If you prefer to book directly, then follow the link to the airline website and book.

FYI, some regional airports show an airport change in London in Google Flights, but once you click through to Skyscanner, there are additional options without the airport change. If your dates don't have an option without the airport change, try adjusting your them by a day or two and you should find routes which don't require one.
