If you've been waiting for something extraordinary to occur which would get you to Europe on the cheap, it's your lucky day!

Base round-trip rates have plummeted to $198 to London and/or Manchester, England.

Yes, there are hefty fees that bring ticket totals up to $773.20, but the offer is still exceptional when compared to other airlines not matching this deal.  For instance, Delta Air Line's lowest round-trip airfare during the same sale period is $1,324.

To qualify for the under-$800 offer, plan to finish your trip on or before June 30. There is no advance purchase required, so go as soon as this week.

Stick with travel Monday through Wednesday or add $25 more each way for other days. Stay one weekend to one month.

This offer is valid on Air Canada (via Toronto); Continental (via Newark); Lufthansa (via Frankfurt, Germany) or United Airlines (via Washington, D.C.-Dulles). Stopovers are not permitted.

But, wait! There's more.

These same carriers offer a steal-of-a-deal rate of $215 round-trip to Dublin and/or Shannon, Ireland. The same rules apply, but a $30 surcharge applies on Friday or Saturday departures and Friday-Sunday returns.

Total ticket prices are $659.50.

These sales have no ticket-by date and are subject to change or vanish at any time. Every seat on every flight is not offered at the lowest rate. Since only a limited supply of sale seats are 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.
