If I fly from USA to India via AI in Business class the size/weight restrictions for luggage are larger than domestic travel. But if I will be also flying domestically in the country, does that mean the business size/weight can't be used at all...and I need to switch to domestic restrictions for the entire trip? That's what I'm guessing, but wanted to know if there's some rule that says if I have an international business ticket as proof it would be allowed on domestic flights? Big hope there, but figured I'd ask. Thanks!
