Narrative:

We diverted into twf after going missed approach due to low ceilings. We landed uneventfully and departed after 90 minutes in twf. Takeoff was uneventful from our perspective. Upon arrival; a nonrev pilot in the back told us he didn't see any runway lighting on departure from twf. The tower was closed in twf at the time; making it an uncontrolled airport with pilot controlled lighting. The captain and I both recall seeing runway lighting when we took the runway; however; the pilot in back said he was approached by two customers claiming they didn't see runway lights.the departure; flight; and arrival from twf were uneventful. I do not remember activating the lights by clicking the microphone in twf prior to departure. However; I specifically remember seeing side lights; runway remaining lights; and runway end lights. Weather; uncontrolled airport; unfamiliar offline airport; and long duty day were all contributing factors. I felt we did not rush; and we thoroughly reviewed procedures for the divert. A good discussion with all involved provided learning lessons in the event something like this occurs in the future.
