For a job that requires 100% travel, it's not unreasonable to want to know how arduous that travel will be, and the arduousness (arduosity?) is heavily influenced by travel policy. To me this isn't about "am I allowed to earn points in my favorite alliance," "can I stay at 5 star hotels," or "can I fly first class?" But it's about "do I have to fly at ridiculous hours or inconvenient itineraries to stay within the limit?" "Do I have to stay at a run-down Days Inn 30 miles from the job site to stay within the limit?" "Do I have to wait 2 months for expense reimbursements?" etc. Some companies have travel policies that make life much more tiring and stressful than it needs to be, and it's completely reasonable to want to know that before accepting a job.

That said, I do absolutely agree that the time to discuss it is when you have an offer, not during an interview.
