And since this is one heck of a steal, we were happy to oblige!Last month, we shared a fantastic TPG-exclusive Singapore Airlines fare to Russia. You can fly round-trip from Houston to Moscow on Singapore’s 777 for just $399, including all taxes. You can travel any time between September 1 and December 1, but the flight must be ticketed by next Monday, August 10. There’s still fantastic availability on this route, with open seats on every date we searched. Keep in mind that flights in both directions are only available on Sunday, Tuesday, Thursday, Friday and Saturday.Fly Singapore’s 777-300ER to Moscow for $399 round-trip. Photo by T.C.

If you book flights departing from another airport (or you plan to visit Russia), you’ll need to get a Russian visa.Here’s an example of the round-trip flight available as part of this deal:Houston to Moscow on Singapore for $399.You’ll pay just $399 round-trip, including taxes and fees, when you book directly through this Singapore page.
