Hi, we will be traveling next May from ORD (Chicago) to NRT (Japan) using AA miles. The only options are business class seats, so we got two business class tickets. However, we are a family of four and thus we will be buying two additional economy class tickets on the same flights. My question is: what is the chance that the two of us in the economy class can possibly be upgraded to business class so our family can all sit together? Or how should we ask so we can maximize our chance of it happening? We have two adults and two kids (7 years old). I know it is probably very unlikely, but if anyone has good suggestions, we would love to know. Thanks!
