Bring the whole family to Europe this fall with wide-open business-class award space

Star Alliance carriers just opened the flood gates and released a ton of award space on popular routes between the U.S. and Europe. While writing this piece, I found four or more open award seats on many flights this summer and fall.

I even found plenty of award space on popular routes like Chicago-O'Hare (ORD) to Brussels (BRU) and New York-JFK to Zurich (ZRH). Some of these routes have as many as nine open seats available per flight.

You can book these awards with any Star Alliance currency. Using ANA Mileage Club will cost you the fewest rewards. But, you can save on fuel surcharges if you book Lufthansa or Swiss-operated flights using Air Canada Aeroplan, Avianca LifeMiles or United MileagePlus.

Best of all, many European countries have reopened to American tourists. So, you may want to use this award space to fly to places like the Czech Republic, France, Germany and The Netherlands. Now, let's take a closer look at this award space and how to book it.

The deal

Airline: Lufthansa, Swiss, TAP Portugal and United

Routes: Dozens of continental U.S. cities to multiple European cities

Cost: From 60,000 Amex points one-way (with Air Canada Aeroplan)

Dates: August through November

How to book: Find award space with your favorite Star Alliance search tool and transfer points to book your ticket.

If transferring American Express Membership Rewards points, you’ll find the best points pricing with ANA Mileage Club. However, you'll pay high fuel surcharges on Lufthansa and Swiss awards. For these tickets, consider booking Lufthansa tickets with Aeroplan or LifeMiles at a higher mileage rate to avoid paying these surcharges. You’ll pay 60,000 Aeroplan points or 63,000 LifeMiles for a one-way ticket from New York-JFK to Frankfurt.

You can also book with United miles, which you can transfer in from Chase Ultimate Rewards. Unfortunately, United charges the highest mileage price for transatlantic awards on partner airlines.

Pay taxes and fees with: The Platinum Card® from American Express (5x on airfare booked directly with the airline; on up to $500,000 on these purchases per calendar year), Chase Sapphire Reserve (3x on travel) or Chase Sapphire Preferred Card (2x on travel) for travel protections on your award flight.

Is it worth it?

Star Alliance business class flights from the U.S. to Germany aren't cheap. Round-trip flights from New York-JFK to Frankfurt start just over $3,281 this September and increase on high-demand dates like Labor Day. This means you're looking at a minimum of $13,000 in airfare for a family of four this fall.

On the flip side, you can book the same itinerary for 120,000 Aeroplan points and $177.02 in taxes round-trip per person. This gives you at least 2.5 cents per point in value, which is a solid redemption for Amex points transferred to Aeroplan.

Plus, Lufthansa's business class is great. You'll be treated to great onboard dining, a comfortable lie-flat seat and access to Lufthansa's business class lounges. You'll also have a solid experience in United Polaris, Swiss business class and others.

Sample itineraries

I found the most Star Alliance business class award space between August and November. And some of these dates have a whopping nine business class award seats available.

Below, I've listed award space for flights with at least four open seats. Note that this isn't an exhaustive list — you may find space from other cities. Many dates have space for more passengers too.

Remember, you can use this award space to connect to other destinations too. Run your own searches to see if you can find connecting award space to your destination of choice.

Bottom line

It's rare to see this much award space from the U.S. to Europe in business class. If you're considering a European vacation this year, consider booking your tickets now before these awards are booked up by others.
