Marathon or Nautilus for plane?


New member
I have both (His normal seat is the MA) I think the MA is waay eaiser to install but is the GN lighter to carry? (I don't have it with me right now its 3 hours away at our new apartment so i can't check) I'll have my DP with me so I'm not too worried about having to carry the seat itself since we'll just check everything else except the seat.. We're flying from FL to MI with (hopefully) no lay-overs! once in MI we're renting a car so the seat will only be installed once while there..

any advice would be great!

(my son is 3- 37 ish pounds and has a short torso (Second shoulder harness slot on the GN)

The GN is just as heavy. If not heavier. And I think the MA would probably install easier on the plane. The GN is really wide and sits lower.

I dunno... just a guess on my part. I've never done either and have no plans to do so anytime soon.

I've flown with both (but only once with each.) I'd say it's kinda six-of-one, half-a-dozen of another. :shrug-shoulders: I'd agree that the Nautilus is heavier, and for the one trip I took with it, I didn't figure out a good way to secure it to the luggage cart we use to haul carseats (I'm sure with more experimentation, I could have.) However, on the plane, having the cupholder was a good deal. :thumbsup: Neither seat will leave room for the child to use the tray table, so having at least a cupholder was nice.

The Marathon is lighter, but still bulky in its own way. I got caught with the buckle issue when I flew with it (not understanding that you can't release the buckle easily once it's installed,) so I'm still shy of it for that reason (even though I understand now how to circumvent it.) I didn't use a cart for it, but carried it in a bag - however I've seen a lot of other parents here have put it on a cart with no issues (or used the GoGo Kidz or Travelling Toddler.)

My son could easily kick the seat in front of him in either seat. :eek: (But possibly, if we had had a Nautilus at the same age we had a Marathon, he wouldn't have been able to reach to kick in the Nautilus.)

I hope that helps somewhat! :)
