From expertflyer only the mar 28 flight is available with 1 bassinet seat blocked. You could try your luck and see if the rep lets you go in.
Ended up swapping to the Mar 28 flight with a downgrade. Got too much invested into this trip and I have three people flying total, so finding space in F is next to impossible.
