Hi - my wife has started a new job that requires frequent trips to Stockholm, as well as (somewhat less frequently) to other European cities. We've been a United family for the last several years, since our home airport is EWR, and her trips to Europe over the last few months - many of them have been on SAS - have gotten her to Platinum on Mileageplus. She's likely to fly on SAS at least 10 times roundtrip to Stockholm next year, probably in business class every time, so I'm trying to figure out if it makes sense to stick with United (since we're already Platinum) or switch to Eurobonus to take full advantage of the SAS flights.
Any thoughts? Let me know if you need more info - I'm not a FF expert but I tried to answer the basic questions from the sticky.
