When I was working all my travel expenses went on a CC, easily over $50K a year, reimbursed by my employer. I’m sure it is that way with a lot of travelers.
The problem is the whole model has changed since Covid - most of the employees (like 90%) are STILL remote and travel is minimal, even among the marketers and sales teams. I’m sure this will solve the problem of overcrowding but it may hurt their ticket sales over all.
