Metered fares are transparent in the same way a car auction is transparent — you find out the total at the end.
For a predictable trip like an airport transfer, the flat rate is almost always the better call. Here's why:
Traffic is not your problem to price. With a meter, sitting in a 401 backup is billed by the minute. With a flat rate, it isn't.
Route choice is not your problem to price. With a meter, the driver's route decision affects your bill. With a flat rate, it doesn't.
Tolls are already handled. Where the 407 makes sense, we include the toll in the flat rate. You don't pay extra for the faster route.
Expense reporting is simpler. One number, quoted in writing, matching the receipt.
The only case where a meter might win is a short, off-peak ride with no traffic — and even then, the difference is usually small and unpredictable. For airport trips, especially long-distance and early-morning ones, the flat rate is the honest choice.
