Is there some trick to getting a first class menu at the beginning of the month? I emailed YouFirst, no reply. I asked the chat, and I was told "I am really sorry, but we won't be able to share the menu for your upcoming flight with you." No explanation or follow-up. Is calling the best route? Or is it really not given in advance?

FWIW, I am looking for LHR to DFW this month.
