How should I actually book this?
Find the cheapest way to pay for one purchase — after the booking channel's price difference and the reward your card earns there. The highest reward doesn't always win: a bank portal's markup and blocked coupons can outweigh a fat accelerator. Markups are research-based estimates (dynamic pricing varies daily) — paste a real quote to firm any of them up. This is separate from the reward calculator; it reads card reward rates, it doesn't change them.
