Are there any travel websites that let me customize searches &
newsletter subscriptions in the following ways?


I'm flexible on departure & return dates when booking airfare.
I want to find a good price. Not specific dates.
When I go to websites like expedia.com, kayak.com, etc
they require specific departure & return dates.

A typical search I want to learn how to do is
"City1 to City2, for 7 to 10 days, anytime in monthX, sort by price"
or
"City1 to City2, for 7 to 10 days, anytime between date1 & date2, sort by price"
or
"City1 to City2, for 7 to 10 days, anytime between date1 & date2, less
than $1000, sort by price"



I also want to subscribe to a travel website's newsletter and customize 
what I want emailed to me. For example, "Send me deals on City1 to City2 and
nothing else". ie. what I do not want is "airfare special to Hawaii"
and when I click the link it says departing from CityX when I want to depart
from CityA.

cheaptickets.com allows you to do searches of the type you describe.
Just click on flexible search.

I hope this helps.

Have a good day.

I have heard good things about this site:
