I want to take Tink with me to Texas in May when my daughter gets married. 

 I would like to take her in the cabin with me, but I don't know how big she's gonna get. She's 4 lbs at 16 wks so I think she's gonna be a big girl.  If she stays small I can get her in a little carry-on bag, but if she gets bigger, she won't fit and she'd have to go in the hold.
 
  
Does anyone fly with their baby? How does it go for you?  It is hard to get them out of the hold when you have to switch planes?
