For those who can't plan ahead, here's another app to help you find travel savings.
Name: Last Minute Travel Deals
Available for: Website (www.lastminutetravel.com), Android and iPhone, iPad and iPod touch
What it does: Accesses flights from more than 175 carriers around the world, more than 100,000 hotels in 153 countries, nearly 20,000 vacation homes and about 10,000 activities. Last Minute Travel is able to offer hotel deals at wholesale rates because it buys rooms in bulk and well in advance of your travel. It is not distressed inventory.
What's hot: My biggest reason to keep this app handy on my smartphone is the "Tonight and Tomorrow" hotel deal feature. I found rooms starting at less than $60 in Atlanta, Berlin, Buenos Aires, London, Milan, Montreal, Paris and more. I also appreciated that I could sort the hotel deals by TripAdvisor rating and not just the usual price and star rating options found on other sites.
What's not: Take the flight search with a grain of salt. When I searched for flights from LAX to London, I found cheaper rates through both Kayak and Expedia. The website version also has travel coupons that I wish were available on the app. If they are, I couldn't find them.
Worth it? Yes. The more deal options the better.
