What are the cheapest flights from the UK to Lima?

You didn't specify dates, so I just used January next year as an example â€" Air Comet sell Lima to London Gatwick via Madrid for £449 one way, but the cheapest return flight is £808 on Delta Airlines, Lima to London Gatwick via Atlanta and back. ...

If you get there and speak only English, you will pay about twice what Thai people pay. ...
