Yeah, I know we have to clear US immigration in YYZ, I've flown via Chicago before on ANA..

Few more questions. Are seat selection on AA free? 2) how much carry on luggage allowed 3)are all seats on the 777 with seat back TV?
I haven't check the other thread i started,so i'll ask again in case no one replied. If I take a connection and it's overnight.. does AA pay for the accomodation or I have to myself?

thanks, i believe the sale ends midnight today..
