Yes, you can travel to any other country if your passport has three or more months until expiration date.
Do you have to renew your passport if it expires June 22 2009 and you are traveling to Spain from March 8 2009 to March 20 2009?
Yes; January is past Christmas and New Year's festivities, when many people leave for vacations; therefore most hotels and flights have discounts during such month. Conversely, there is a festivity around March 21 when Benito Juarez birthday is celebrated; also Spring Breakers flee to Mexico during the last days of such month.
