But airlines are releasing travel waivers to allow flexible travelers the chance to rebook themselves on flights through other airports or on other dates.Note that you can sometimes get quite creative with these travel waivers, as TPG’s own Zach Honig did recently on his HNL-EWR flight. He was able to succesfully change to HNL-MAJ-KWA-KSA-PNI-TKK-GUM-NRT-EWR, before having to change it back due to work scheduling conflicts.If you can’t delay your itinerary, some top cards have flight delay/cancellation insurance that can reimburse you for weather issues, including the Citi Prestige ($500 per passenger for 3+ hour delay), the Chase Sapphire Reserve ($500 per ticket for 6+ hour or overnight delay) and Chase Sapphire Preferred ($500 per ticket for 12+ hour or overnight delay).The following airports are covered by at least one of the waivers below:As of this writing, here are the available travel waivers for Sunday/Monday:American AirlinesSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
