Looks like you'll have quite a way to go so, in my opinion...maybe! Kinda depends on how your family handles long flights. My wife would be mostly un-able to function after a long flight and tends to feel ill if she doesn't get some descent rest so, for us, it would probably be worthwhile so that she could enjoy the trip more. We've flow business class for this reason to Europe and will again soon. soon. Me, personally, I've done long flights in coach and, while it's not the most comfortable, I'm more willing to tough it out and can still function on the other end. Flying domestically here in the US, other than, maybe coast to coast, I would probably say no but for us in the Central US, it's 3 hours to Florida, 4 hours to California. Probably not worth it. A long trip though...I'd probably go for it and expect the big bill!
