Which airine do I pick??
 

As a newbie, I have to take 5 family members from the us to Europe. The fares are pretty much similar between all the companies.
Which airline should I go with that I would be able to use the miles to travel more?
What is your opinion?

US are a big and Europe isn't that small as well... so where to you start and where do you want to go?

Your departing airport is an important factor in the equotation as long as you don't want to have to many stop overs to get to next airline hub.

That depends very much on what routes you would like to redeem miles for in the future. A single roundtrip in Coach will not earn very many miles per passenger. However, there are a small number of frequent-flyer programs that let you open a "family" or "household" account, and pool everyone's miles to have enough for one or more redemptions. Some programs assess very high cash surcharges on some redemptions; others do not.

Do you plan to take advantage of any of the numerous mileage bonuses offered for credit-card sign-ups?

I'd like to fly MCI-CDG. Family accounts sound good, I will check into that. We have a family account with BA. As far as CCs go, I just did the personal & Business SW offer, so I am unable to open another Chase at the moment since I just opened 2 this month. I also just got Barclays.

What is the difference in price between flights for all 5 people?

I'd pick the cheapest unless the difference is small, in which case I'd go for BA because of the household account and low redemption prices.

2.British Airways.
3.Air France.
