The pandemic wreaked havoc on the travel industry in 2020: international travel all but halted for many countries; airlines filed for bankruptcy protection; traditional tourist hotspots have become coldspots. In response, the travel industry has been forced to rip up big chunks of its playbook and start fresh. One idea gaining traction? Travel subscriptions. Costco has partnered with WheelsUp to offer a yearly private jet subscription for $17,499.99. Tripadvisor is launching a yearly subscription service called Tripadvisor Plus for $99, which offers access to travel deals and other perks.
