Positioning Flights: When Saving Miles Costs More

A concrete award-trip example showing when reaching another departure airport costs more than the miles saved.

Priya has found the award she wants: a one-way seat to Europe, in a cabin she’s happy with, on a date that works. From her home airport it costs 60,000 miles plus $80. Then she spots the same kind of seat from a big hub a short flight away for 45,000 miles plus $80.

Using 15,000 fewer miles is only one part of the price. But getting to the hub means a separate flight there, a hotel the night before and a bit more ground transport. This guide works through whether that trade is worth it. Priya, her airports and every price below are invented for the example; no live fare or award was searched.

Positioning, briefly

Here, a positioning flight means a separately booked flight to the airport where Priya’s main award itinerary begins. It gets her to the hub so she can use the lower-mileage award.

Priya’s two options

Both options get her to the same destination, in an acceptable cabin and date window. The model uses the same fictional airline-mile currency and assumes both awards are bookable. The home-origin award covers the journey from her home airport; the hub-origin award starts only after her separately booked positioning trip.

All listed amounts include the fees she’d pay, including a checked bag on the positioning flight. Anything not listed is assumed to cost the same either way and is excluded. These are the costs being compared, not her complete holiday budget.

Cost From home From the hub
Miles 60,000 45,000
Award taxes and fees $80 $80
Positioning flight (with bag) none $140
Hotel the night before none $100
Extra ground transport none $30
Cash total $80 $350

The hub option: $80 + $140 + $100 + $30 = $350.

So the hub keeps 60,000 − 45,000 = 15,000 miles in Priya’s account and costs $350 − $80 = $270 more cash.

What she’s really paying for those miles

The useful number is what each saved mile costs her in cash:

$270 ÷ 15,000 miles = $0.018 per mile, or 1.8 cents per mile.

That’s the break-even. If 15,000 miles are worth more than $270 to Priya, positioning comes out ahead in her value comparison, despite requiring more cash. If they’re worth less, she’s paying too much to save them.

There’s no universal answer to what a mile is worth. It depends on what else Priya would do with those 15,000 miles and what that would otherwise cost her in cash. The same flight, different miles shows how to compare bookings on that basis. Here are two invented personal values to test how that assumption changes the answer.

If her miles are worth about 1.2 cents each to her: 15,000 × $0.012 = $180. She’d spend $270 to keep $180 of value, so positioning leaves her $90 worse off.

If they’re worth about 2.0 cents each: 15,000 × $0.020 = $300. Now $270 keeps $300 of value, so positioning leaves her $30 better off.

Same trip, same prices, and the decision flips on a single assumption. That’s why the mileage saving on its own doesn’t settle it.

What the comparison leaves out

Even in the 2.0-cent case, $30 is a thin margin. The comparison includes cash and Priya’s assumed value of the miles she keeps; it assigns no price to extra time or disruption. The hub option also costs Priya:

That second point matters more than it looks. British Airways, as one airline’s example, says that if you’ve booked separate flights with different booking references, each flight is treated as a separate journey, even if all of them are with British Airways. You collect your bags and check them in again for the next flight. It also says that when a separately booked first flight is disrupted, airlines are limited in the help they can give for the onward flight (BA: baggage on separate tickets, last updated April 24, 2024).

If you miss a connection you booked separately with another airline, BA says to contact the airline you booked that flight with (BA: missed connecting flight, last updated October 5, 2023).

Those are one carrier’s statements, not rules for every airline, and they don’t settle what refund or rebooking help Priya would get in her own case. Her model includes arriving the day before and paying for a hotel. That overnight stay is a planning choice, not a guarantee that a disruption would leave enough time to make the award flight.

Only Priya can price the extra day and the extra booking. This example doesn’t put a dollar figure on them. A $30 margin is easy to lose to either.

Keeping cash in reserve

Suppose Priya wants an additional $200 set aside for a positioning disruption, above any emergency funds she’d keep for either itinerary. For this part of the trip, she needs $350 + $200 = $550 available for the hub option: $350 in planned spending and $200 still in reserve. The home option’s compared spending remains $80; that does not mean the home option needs no emergency funds.

The extra $200 is an invented reserve, not money already spent, an expected loss or an estimate of an adequate emergency fund. It stays out of the 1.8-cent comparison unless it is spent, at which point her actual costs change. She must still be comfortable making $550 available for this part of the hub option. For some travelers that cash requirement rules it out.

Priya’s decision

Priya values her miles at about 1.2 cents, because the cash trips she’d otherwise use them for are modest. At that value the hub costs her $90 more than it saves, plus a day and a second booking. She books from home.

A traveler who values miles at 2 cents or more, has a flexible day to spare and doesn’t mind an extra night could reasonably choose the hub. The method doesn’t change, but the answer depends on the traveler.

Running your own numbers

  1. Price both options to the same destination, including every fee and the bag on the positioning flight.
  2. Add the hotel and ground transport you’d actually need.
  3. Divide the extra cash in dollars by the miles saved, then multiply by 100 to express the result in cents per mile. Here: ($270 ÷ 15,000) × 100 = 1.8 cents.
  4. Compare it with what those miles are worth to you, then decide whether the extra day and separate booking are worth the difference.
