I work for a big 4 consulting firm, we've been the largest client for several domestic airlines and hotels for years. Publicly we've indicated there will be zero travel unless it goes through significant approvals until at least early next year. In private weve got multiple initiatives stood up to make remote first the reality for years to come. Our clients are way too excited by the cost savings and are more comfortable with not having to manage consultant access, space, etc. In fact our business is booming with clients who want help setting themselves up to be remote capable.
In addition, all of our conferences have gone digital, our space dedicated to in person training classes, client greenhouses and workshops is being closed and repurposed, rumors of it being sold even. Business travel is beyond dead. Companies are realizing it just doesn't make sense (it never did), and there's too much to be saved by offloading building and real estate costs.
