Today's travel deal is short and very sweet.

Travel round-trip to Tokyo, Japan this month at an amazing base rate of just $199.

Rules are simple: Give at least a three-day advance purchase notice. Depart any available day of the week through July 31. Stay any three nights to one month.

Factor in all of the taxes, fees and surcharges for a total ticket rate of $877.50.  That's crazy, isn't it? But compare this sale rate to Delta's of $1,763.50 for the same travel period.

This offer is valid on United Airlines. United serves Tokyo with one flight connection in Washington, D.C.-Dulles Airport.

Sale airfares are always subject to change. Every seat on every flight is not offered at the lowest rate. Since only a limited supply of seats is available, act quickly to make your purchase.

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 Web sites such as Expedia or Travelocity, etc. Airlines can discontinue or pull a sale price without notice when the offer does not have a "ticket-by" date or when the offer is deemed "sold out."
