We (my wife, myself, two kids 7 & 11) are flying out of Orlando to
catch our SAS-flight from Newark back home to Copenhagen. Our
SAS-flight leaves Newark at 17.50 (same as 5.50 PM ?).

Now, Song or Continental will fly us directly to Newark for 480$
total, while Jetblue or Song will fly us to JFK for only 350$ total.

If we fly to JFK we would of course have to allocate time to transfer
to Newark.

What would you do?

You would also have to allocate money in addition to the time to travel
between the two. So, determine the costs involve and then determine
whether saving $130 (less the transfer costs) is worth the convenience
(to you and your family) of not changing airports.
