On KAYAK you can create one by signing in and going directly to Price Alerts in your account or you can look for the "Track Prices" button on the top left-hand side of flight results. If you're searching hotels, select "Set Price Alert" at the top right of the hotel results list. If you're on our app, you can get to Price Alerts using the app's navigation menu and follow instructions there.
With trivago you can easily find your ideal hotel and compare prices from different websites. Simply enter where you want to go and your desired travel dates, and let our hotel search engine compare accommodation prices for you. To refine your search results, simply filter by price, distance (e.g. from the beach), star category, facilities and more. From budget hostels to luxury suites, trivago makes it easy to book online. You can search from a large variety of rooms and locations across the USA, like San Francisco and Chicago to popular cities and holiday destinations abroad!
Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you flights up to 3 days before/after your preferred dates. That way, you can see if leaving a day or two earlier will find you a better deal. You can also select the flexible "weekend" or "month" search options to widen your search range and find the cheapest price that works for you.
