rePOttINg iVY baBY

I noticed that the ivy's root has starting to come out from the bottom of its original pot, so I decided to repot it. I bought my ivy baby a bigger pot, which I later found that it might be a little bit bigger than the next pot it supposed to be repotted. But, oh well, he's gonna be happy to find all the extra space in the new pot, I hope.

It was fun to move my ivy baby to its new home. But I'm just wondering--can I bring him onto the airplane with me when I'm ready to travel back home?
??

P.S. The Ceneria baby I bought along with the ivy died a week after it got home. I think I'm not really ready to take care of flowers. :(
