// ==UserScript==
// @name           Orbitz.com flight search
// @namespace      OrbitzSearch
// @version_timestamp 1242917549147
// @description    Search orbitz.com plane tickets with different dates.
// @include        http://www.orbitz.com/*
// ==/UserScript==

/*

To use:
Do search for flights on orbitz.com
Click "start search" on the results page.

The search will start around the departure/return dates you have picked until orbitz returns an error when the search reaches today.


To try to guess the best season of a year...
* Change the "move ... per search" box to 30 days.
* Change departure/return dates to 6 months away.
* Click "start search"
This will do searches in 30 day gaps.

* Note: if you search too much as a non-member eventually they'll ask you to join.
