A. You'll find this information in the fare details. There we provide you with information regarding the availability of the fare, as well as travel period, and days of the week on which this fare is valid for travel, along with any other notes or tips we may have regarding that fare. Better still, we always provide links to the airline or travel site where you can book the fare.

And remember, fares can change several times a day, meaning you should pounce on those fare alerts the moment they arrive in your inbox. There's no guarantee that a fare from yesterday's alert will last through the following day.
