How can you find the most reasonable air fare??? I have been searching, but think I can do better.?

You want to buy early, be flexible with your travel dates and fly during off-peak travel season. Also subscribe to different travel website newsletters or airlines to send you emails/alerts of fare sales.

Depends on what you define as "reasonable".

If you think you can do better, you most probably have been paying attention to the recent increase in fares do to fuel costs and the start of summer travel.

Airfares vary depending on time of year, demand, etc.

Since you do not indicate where you are flying from or to, it is difficult to give specific advice, but if you have not already done so, check the travel websites like Expedia, Travelocity, Orbitz, etc., and the websites of the low fare airlines that serve your closest major airport.

While you are checking fares, register for an account and sign up for fare alerts based on your travel criteria.

Book 8 months or more in advance is the only sure way of getting the best fares.
