Beyond-Paris tickets can undercut SFO–CDG: test Athens, Rome and 12 other onward cities

Asked (summary):
Booking an Air France reward ticket, the nonstop SFO–CDG is about 80k miles while SFO–CDG–Florence shows about 38k. Which other non-obvious cities beyond Paris are worth checking for an even cheaper rate?

The shortlist covers 14 European cities with reported Flying Blue award pricing, or explicit reports of cheaper pricing when continuing beyond Paris — the cities worth searching, not all that exist. All miles are historical examples from different origins, dates and cabins: reported examples, not live SFO quotes. The page also summarizes the official Flying Blue stopover rule and Air France's US conditions on skipping segments.

Where to point the search: 14 onward cities, keyed by cheapest reported award

Wave 1 — under 20k miles reported (search first) Wave 2 — 20k–50k reported Wave 3 — 60k+ reported (mostly business-class examples) No miles figure — reported cheaper onward, still worth a check

What the map cannot say

Athens is the most corroborated test: 26 separate mentions, with JFK–CDG–Athens reported at 18,750 miles in economy — flightpoints.com
The lowest figure of all is London at 12,000 miles — RDU to LHR connecting in CDG priced below the Paris-only ticket — reddit.com
Flying Blue officially books a complimentary stopover of 24 hours or more in Paris — by phone through customer service, paid in Miles or Cash & Miles — flyingblue.us
Skipping the CDG–destination leg is not risk-free: Air France's US conditions require full, sequential coupon use, list a €500 economy / €1,500 business intercontinental non-compliance fee, and a €400 fee to collect checked bags after cutting a trip short — wwws.airfrance.us

Two ways to use a cheaper beyond-Paris fare

Safe: fly it all, or add an official Paris stopover

Flying Blue reward tickets can include a complimentary stopover of 24 hours or more during a connection between two flights on Air France, KLM or partners. Log in and call customer service via the “Contact us” page; they make the arrangements. Original reward-ticket terms still apply. flyingblue.us

So a Florence-style ticket can legitimately become a Paris trip: stop 24h+ in Paris, then continue — or simply fly the whole routing and enjoy both cities.

Risky: hidden-city skipping of the last leg

Air France's conditions say the fare is valid only for a ticket used fully and in sequential coupon order. Non-compliant use carries a fixed fee at check-in — €150/€300 within Europe, €500/€1,500 intercontinental by cabin — and collecting checked baggage after cutting the trip short may cost €400. A missed segment can also cancel later segments on the same ticket; separate one-ways are safer. wwws.airfrance.us

Search workflow

1

Price your baseline: SFO–CDG nonstop, one-way, one traveler, your date and cabin.

2

Re-search SFO to each wave-1 city (Athens, Rome, London, Brussels, Naples) on the identical date and cabin.

3

On each result, open flight details and confirm the long-haul leg is the nonstop SFO–CDG flight you want.

4

Compare miles and taxes together — a cheap mileage price can hide higher surcharges.

5

If nothing beats the baseline, continue through waves 2–3 and the no-figure cities (Madrid, Barcelona, Stockholm).

6

Found a winner and want Paris itself? Call Flying Blue to add the complimentary 24h+ stopover before continuing — do not plan on just skipping the last leg.
