Even though my wife has the personal Chase United MileagePlus card, she was able to apply for and be accepted for a Business MileagePlus card because of our small business LLC. I work at a company but our small business is still active on the books so Chase accepted us!
Now we must use it for $1000 of spending as quickly as possible so that the 30K miles get deposited in her account. Then as far as I can see, I can push out the return flight from Berlin to two or three days giving us the time we need in Berlin to really see it all. I'm praying that things will work as hoped.
I checked the availability and there are plenty of seats at the Super Saver award level. Probably because the planes are so big....in fact I am looking forward to flying home from Frankfurt on their 747-800. As a high school student I flew on the very first 747 which landed and took off from Indianapolis International Airport. I later flew with my wife to Europe on our honeymoon on a 747 out of NYC. So I have great memories and will now share them with my 21 year old daughter flying home from our visit!
Thanks for the conversations and recommendations!
