FareAlert You don’t need to fill in cities and times, and refresh your search again and again to find the cheapest price on Ctrip. Just add a domestic route entry in our FareAlert and tell us the lowest price you are willing to pay. As soon as prices drop, the matched flight information will automatically jump into your mailbox!
DealFinder This is my favorite tool, and the easiest one to use. Anytime you search for a flight, just click to expand the DealFinder calendar at the top of the results and you’ll see the lowest price of each day over the 2-week period around your departure date. If your trip is flexible within a short period, you can grab the lowest price right then and there!
Good luck, and happy booking!
