"I had heard they will take the stroller at the entrance of the plane and will give it back when you are going out. Is'nt it true?? " Yes, it is true and when you get off the plane they will put those strollers in the entrance, I had no problems going to nepal with but when I was coming back my stroller got lost so you just have to remind the air crew before plane lands so they make sure that you get your stroller. Yes, it is better to have your baby passport, otherwise you they can give you hard time. IF I were you, atmaram I will wait until my baby is little older becasue at this age s/he is still developing immune system and taking baby to other place can cause illness and stuffs. Some planes provide baby food but it is always best to take your own formula and baby food ( incase your baby does not like other food than what he is used to). IF you book your tickets in advance, you might have better chances of getting the very front seat with some extra space. Well, good luck!!
