Expedia Inc. announced two new deals Wednesday that probably made the online travel agency?s rivals cringe a little.

Bellevue-based Expedia said it will offer a free night at 700 participating hotels when a customer books a stay of three to five nights. The company also will waive airline-booking fees on all flights booked before May 31.

?A silver lining for consumers amidst the current economy is the incredible value available in travel right now. In some popular destinations hotel rates are down by over 20 percent," said Tim MacDonald, general manager of Expedia.com, in a statement.

The move put pressure on Expedia rivals including Orbitz Worldwide Inc. of Chicago, which saw its shares fall nearly 25 percent in Wednesday trading, falling 50 cents to $1.52, and Priceline.com Inc. of Norwalk, Conn., which saw its shares fall nearly 7 percent, dropping $5.57 to $75.71. Expedia shares rose nearly 1 percent in Wednesday trading, rising 7 cents to close at $7.12.
