When I was a regional FO flying from YYZ to EWR, there was a pretty decent snow storm at departure. We were in a long line awaiting deice and inflight called us to say a younger female was having some anxiety issues. Captain was older and furloughed ATA CA and asked to speak with her on the inter phone. She explained she was supposed to be flying private but couldn’t at the last minute because of weather. She also said she was on the phone with her boyfriend who flies private and listed the reasons why he said our flight was a risk and a no go for any sane pilot. She was wound up that regionals weren’t safe and that the crew was inexperienced and that the go decision was putting everyone at risk. The weather was standard snow with winds below 20 knots, something like 500 over and 1/2 mile or so. Certainly something we could depart in. Captain finally calmed her down and let her know his experience felt the situation was well within acceptable limits on all accounts. He was a great guy, retired AF and last flew left seat on AF2 before a good stint at ATA. Never once mentioned any of that to her, just did his best to assure her she was in good hands. At the end of the conversation we pull from her she usually flies private with her boyfriend in control (we assumed 91 corporate) but in actuality private pilot, in a high wing Cessna.
