Just as some feedback, it saw that I was based in London, auto-selected Heathrow as my base airport and the first trip it offered me was a $800 trip to London. Don't think I'll be taking you guys up on that offer.
And I would also like to see the code LON for all airports around London. If I am to take a GBP 5k trip to Fiji, I don't really mind if it starts from Heathrow or City of Gatwick :)
Had a similar experience where I live. It looks like the algorithm decides you don't need a flight to where you live, just a hotel, so the overall amount ends up cheaper. Switching from Flight + Hotel to Flight Only gave me a more meaningful result.
