That will be a long trip.
Find the bag you want to use and start carrying your baby around in it every chance you get so they get used to it. I used to keep the bag on the sofa and hid treats join it so mine would get in and out of it for fun.

I started traveling when mine was very young so it is kind of old hat for her, but I suggest you go to your vet and see if they recommend something in case your pup gets restless or scared. You would hopefully not need it , butmwouldmhave it if you needed it.

Is she piddle pad trained? What will you do finished needs to go to the bathroom. Again, mine uses piddle pads so I just take her to the bathroom on the plane and tell her to "go potty" then just dispose of the pad where ever people dispose of diapers. If you have layovers some airports have outside potty areas, but you might have to come and go through check-in to get to them.
