names on passports and airline info

[Dznypal]

I am booking our air for our cruise thats coming up

were on british air but Im a bit confused on how to fill out the booking info

it ask for the first names there is an "S" at the end like its looking for 2 first names
it also says names to match documents

but on our passports it has our first name and middle name on the same line that says given names again with an "S"

Im assuming we put both our given first name and middle name on the same line like it is on the passports
actually as IM typing this I think I answered my own question
so am I right on this
I just dont want any hassles
its probably not a big deal to include the middle name just hoping Im putting it in the right place
thanks all

The third word on the given name label is, "Prénoms," - literally French for, "First Names."

When filling in passport information, if you only have one box, regardless of whether it says First or Given, everything on the, "Given names/Prénoms" line goes in there.

If you have a separate First and Middle box, then split your names. It has been at least two decades since I've seen this format in a form, and it was deprecated ages ago, but when dealing with governments you never know when some old form might come up.
