One sidenote: if you do get a G-Luxe or G-Lite, be sure not to leave the coffee cup holder on when you gate check it. We lost ours that way, and somehow can't bring ourselves to spend $20 for a replacement from Uppababy.
The G-Luxe became my daughter's primary stroller from ~6.5 months. 4.5 months might be pushing it a little, but fully reclined it should be okay.
And definitely agreed on taking off the coffee cup holder before gate checking.
