JetBlue's Commercially Questionable Slots in Amsterdam

JetBlue has secured commercially questionable slots in Amsterdam. The slots made sense for flyby if they were operating to the UK. But basically this would require JetBlue to leave New York at something like 2 a.m. arriving 3 p.m. departing 4 and arriving back at New York at like midnight or something. I'm sure people would book them if the price is right.
