Which carseat for airplane?



I'm traveling with my 4 and 6 year old on southwest. My 4 year old definitely needs a seat. He is 38" and about 30 pounds. I have the Graco Size 4 Me or the Harmony Defender. Are either of these Ok for the flight or do I need to buy something different that is more narrow or lighter? The 6 year old may or may not need one. She is about 42" and 38 pounds. I know 40 is what I see recommended for when she could just ride in the plane's seat, but was wondering if there is any variation on that. I'm hoping I don't have to bring a car seat for her too, but if I do, she uses the Graco Nautilus, which is super heavy and one I wouldn't really want to use.

We will not need car seats when we arrive so this is only needed for the flight itself.

Also, as a side question - how do you carry your car seat through the airport?
