Sling vs stroller at the airport

We decided to get a lightweight travel stroller before our most recent trip to the US. We’ve loved travelling with our everyday ones, but thought a lightweight one would be better with getting in and out of taxis, around towns and all over. One test we had was to see what it was like taking it through security to the gate instead of checking it all the way through, like we’ve done in the past.
I thought I’d summarise it up with a list (albeit short) of pros and cons. It’s a very short list but I think it covers most things.

Pros

Save your back by not slinging
Somewhere to hang/put bags

Easy to take straight to gate

If you’re travelling alone, seems a lifesaver when you don’t have those extra pair of hands

Cons

If your baby is sleeping when you go through security, he’s got to come out of the stroller (and risk being woken) so it can be x-rayed

You’re typically the last person off the gangway (waiting for them to get the strollers from the hold)

One extra thing to have at the plane and deal with when there’s a sleepy/hungry/antsy baby

My final verdict – check the stroller in and use a sling. You have two hands with a little one in a sling and won’t be the last person off the plane.

But that’s just my opinion.
Do you have any other pros or cons on using a stroller at the airport?
