Follow The Points Guy on Facebook and Twitter, and subscribe to text message alerts from our deals feed, @tpg_alerts.Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using the American Express Platinum Card, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.With the bomb cyclone hitting the US East Coast in full force and cancelling thousands of flights, warmer destinations are top of mind.
