In the past seven months, FCF has written seven special reports for oneworld (American) and Star Alliance (United) members looking to deploy miles in order to achieve or maintain elite status while flying up front.
In December, we focused on American to Europe, in January to Asia on American, in February to South America on American, in March on the Transcon on American, in April to Hawaii on American, in May to Asia on United, and in June to South America on United.
By the way, many of these tactics also work for anyone who can’t find a low Business Class fare, and for those who don’t even have many American or United miles.
SAME APPROACH APPLIED TO UNITED’S EUROPE ROUTES
Our pitch: As we’ve been saying, you might want to forget about free mileage awards because they don’t earn elite credit, and it can be difficult to find free award availability. Instead, use miles to upgrade because availability is much greater, and you earn miles and elite credit.
UNITED’S UPGRADE PROGRAM
To upgrade to Business Class to Europe, United requires 20,000 miles plus a co-pay of $550 each way on the lowest upgradeable economy fares (W, S, T, K, L, and G). When Business Class fares are high, using miles for an upgrade can offer a great return.
HOW TO SAVE 62% ON HIGH-FARE ROUTES
Say you’re traveling Chicago to Munich, often an expensive Business Class route, even when booked way in advance. The lowest United economy fare is currently $768, while Business Class is $4,909 ($4,141 more). So, even with the $1,100 co-pay, you can save $3,041 (62%) off the published fare by using miles. (See chart below for upgrade award availability survey.)

LOW ECONOMY ROUTE SAVES 56%
San Francisco to Paris is one of United’s lowest economy fare routes, currently starting at $628 round-trip, while Business Class is $3,910. Even with the $1,100 co-pay you can save $2,182 (56%) off the published fare by using miles to upgrade.

BRIDGE ROUTE CONNECTIONS CAN SAVE UP TO 54%
Smart travelers use the long-haul Business Class flight as a “bridge,” which means getting the premium seat on that leg, the one that matters most, and using economy to reach the gateway.
From the U.S., that means you should consider buying an economy through-fare ticket, meaning a fare that includes the entire itinerary on one ticket. If upgrade space is available on the domestic segments, grab it, of course, as the cost is the same.
Example: On Fort Lauderdale-Madrid the lowest through-fare ticket (connecting via Newark) costs $698 in economy, instead of $3,902 in Business Class. Even with the $1,100 co-pay to upgrade the long-haul segment (Newark-Madrid), you save $2,104 (54%) off the published fare by using miles.
Use our survey below to have an idea of upgrade availability on the long-haul segment.
WHAT TO DO WHEN AN UPGRADE IS ONLY AVAILABLE ONE WAY?
United lets you combine economy and Business Class fares, so you can upgrade the flight-segment that has upgrade space and book the other leg in Business Class. On Chicago-Frankfurt, the combined coach-Business Class fare is $3,353, while round-trip Business Class is $4,923. So, even with the $550 one-way co-pay, you can still save $1,020 (21%) by using miles one way.
TRAVELING ONWARD IN EUROPE,
BUT NOT ON UNITED?
It’s easy if you stick with United’s partners, and book the entire trip on one ticket, in coach or Business Class, and just upgrade the United Transatlantic segments. Book the routing in coach based on the availability of Business Class upgrades.
Lufthansa: Flights to other destinations in Europe from Berlin, Frankfurt, and Munich include: Athens, London, Cyprus (Larnaca), Moscow, Prague, and countless others.
SWISS: Flights from Zurich include: Amsterdam, Bucharest, Dublin, Malta, Oslo, and countless others.
Brussels Airlines: Flights from Brussels include: Lyon, Milan, Nice, Stockholm, Venice, and many others.
How you can get almost anywhere on one ticket: Say you want to fly from Newark to Riga (Latvia). On United, that could mean making a connection in Frankfurt.
The lowest upgradeable economy through-fare is $834 round-trip versus $3,878 in Business Class. You upgrade the bridge legs of the trip, Newark-Frankfurt-Newark, which is easy by referring to our cheat sheet below, which reveals the best months for upgrade availability.
Even with the $1,100 co-pay (plus 40,000 miles), you can save 50% ($1,944) off the published fare by using miles. Note that the connecting leg (Frankfurt- Riga) will be in economy on partner airline Lufthansa.
