I have worked for similar consulting companies, though not AWS. We had to always book an initial ticket that was policy compliant (economy, or higher only if it was similarly priced), and then optionally upgrade the seat. That causes the upgrade to come through as a separate charge.
Later, when submitting expenses, the upgrade had to be marked as a personal expense, to be netted against per diem or paid back directly.
Early in my career managers did a very poor job of explaining that this was allowed.
