Two extraordinary airfare deals are up for grabs today from American Airlines.

The carrier offers a one-way sale rate of $68.80 to New York-LaGuardia and $74.60 each way to Detroit. These bargain rates are valid on Tuesdays, Wednesdays, and Saturdays when tickets are booked one-week or more in advance.

These rates can be booked today for travel finished on or before Oct. 30, 2013.

Naturally, there are a number of blackout dates to avoid: Dec. 21, 22, 26, 28, 29; Jan. 2, 5, 6 and March 8-10, 15-17, 22-24, 28-31.

American offers frequent daily nonstop service between Atlanta and New York. A connection is required in Chicago-O’Hare en route to Detroit.

The deal to New York City represents a significant savings - particularly since you can take advantage of American’s frequent nonstop service. Consider buying tickets today for your spring through autumn visits to the Big Apple. Other carriers (AirTran and Delta) charge a minimum of $300 per round-trip during peak tourist seasons. As well, one-way rates to Detroit average $150 during most seasons.

This AA sale has no ticket-by date which indicates the offer could vanish at anytime. Act fast to make a purchase.

Sale airfares are always subject to change. Every seat on every flight is not offered at the lowest rate.

I recommend starting the search for available seats at Kayak.com vs. calling an airline directly. You can also search for the sale at travel websites such as Expedia, Orbitz or Travelocity, etc.
