Iberia airlines with a newborn baby?

Hello! We found a good deal from the USA -> Barcelona on Iberia airlines, non-stop. We were thinking of traveling with our 5 month old newborn baby.

1 - Does Iberia airlines have bassinets like other USA airlines? I did a search and didn't find anything

2 - Is there anything to watch out for when traveling with a baby internationally to Spain? First time potentially going to travel with baby!
