Kourt and her husband, Travis Barker, reportedly flew Alaskan Air for a trip from LAX to Spokane, Washington earlier this week. We’re told Penelope and North were also on board. They appeared to be keeping the whole thing low-key, wearing their masks and hoods. We know they have a home in Coeur d’Alene, Idaho and Spokane is the closest airport. So, they are likely to spend some time there. Of course, commercial cruising isn’t exactly her family’s MO lately. Remember, a recent report by Yard, a marketing firm, called out celebrities for polluting the air by taking private jets. Kim Kardashian and Travis Scott were among the celebs who made the list — and, as we mentioned, Kylie Jenner’s carbon footprint was also a hot topic after she posted a photo of her and Travis on their private jets. She also got a citation for allegedly using her PJ’s to go shopping less than 30 miles from home … just to avoid LA traffic. It’s safe to say that Travis and Kourtney are doing everything they can to stay off the planet’s polluter list!
