Oh thank you! In that case, that's reassuring. We are 744 on YVR-FRA and 748 on FRA-DEL.
On the 748, I am frantically trying to get to F but no availability on the day I am flying lol.
We will carry it as planned, and if he doesn't like it -- we can take it off. Evenflo is similar to Cosco I believe, quite small. Off hand, i don't remember how big the wide body compartments used to be. Been a while since I flew a 747 and all my J flights were on 777.
