I'll be in ARN in July and need to get the family (4, 2 kids) to CHS. Some exceptional J fares out of ARN.

A one stop (albeit with a 4 hour layover) on BA CW is 10% more than a two stop with LH or LX, or UA. I'm trying to decide between them. I know CHS is a second tier destination for BA...what's it like now versus what *A can offer?
