My wife and our two teenagers are planning to fly as Delta family and friends to Tokyo on July 3 and back on July 18. The flight there looks "good", the flight back looks "fair". Suppose we have trouble getting back. Is this direct flight to ATL the only flight we could fly standby on or would Delta try and get us on another flight, perhaps on another airline, to some intermediate destination like LAX? Any suggestions/observations welcome! - Greg
