AIBU for not checking on DH and the kids during flight?

[Dhflightsulk]

We recently returned from an abroad holiday, we left the online check in too late which meant we had 3 seats next to each other, and then a seat further down the plane about 15 rows in front, as opposed to next to the 3 on the opposing row (as we did on the way out).

I took the single seat and DH was with DS2 and DD5 in the three.

The flight was only short haul so about 2.5 hours. DH was (and to an extent still is) unhappy that I didn’t check in with him during the flight, which he described as hard work with our kids being young.

I said he’s perfectly capable of parenting and didn’t need me checking up on him. He maintains I should have checked in.

AIBU?

She was a couple of rows away not on a separate flight I really dont get the big deal

They were sitting near eachother on the outward bound journey she says in her OP?

And why weren't they sitting near each other on the return then? Because HE didn't bother to book the seats
