Can you gate check a stroller and a car seat? We have 3 tickets on Northwest and I looked on their website and it doesn't say anywhere if you can gate check both. My son is way too tall to use the car seat on the plane but we need it for the rental car. Thanks. Also according to Northwest airlines website if you booked your tickets before March 29th you can use the old rule of 2 bags per person. Just thought I would share.
, but gets the job done.
