How to get a cheap flight to europe from austin, texas?

I am going in either september or october and want to be gone for two weeks. So far, I've seen 800$ flights from austin to london.

what part of the month/week is the cheapest to fly?
which site has the cheapest and best deals?

This can change from day to day. YOu just have to keep looking or go to a travel agent. The sooner you get your ticket, the better. Good luck.

This should help: http://www.farecompare.com/maps/myAirportCategoryMap.html?departure=AUS&category=E urope -- Adjust the outbound dates there and click "change." After you choose a specific route, Farecompare shows fare history, current prices for upcoming months, allows easy sign up for sale alerts, and compares your itinerary with several different providers (click the ones you want), all from 1 page. Use this, then when you narrow in on a specific itinerary (cities and dates) run it through http://www.bookingbuddy.com -- Doing these things will, I believe, get you the absolute best fare for this itinerary.

Even though Austin is growing by leaps and bounds flying out of Austin to connect to a European bound flight will be costly. Drive to Houston. It is only two hours away.

http://airtickets.fateback.com - try this one. I personally use it to find cheaper flights.
