Mr. CtLawyer. Not calling you to fly Spirit. You could still say thanks for the rest of the Jewish people. Also, without Spirit, you would not get a chance to brag about your fancy travels! I proudly flew Frontier for $40 on business, saving the client’s money, not that they cared or noticed. The alternative was to stay till the morning, bill for a nice hotel. I decided it would be a good musar for myself to do what I would have done if I were paying on my own. I was the only one in a suit on that red eye, everyone else weared T-shirts.
One of the reasons was probably because I had an un-fortune to attend a learned class about business halakha. The speaker discuss a lot of proper humrot in dealing with the opposite sex and drinks in non-kosher places, and then some kulot in dinei mamonot, such as – can you bill 2 clients for the same trip when you visiting them both, or can you bill your company for fedexed kosher food, if it was delayed and hotel reimbursed you. He did not allow much after some pilpul. After than a local Rosh Kollel interrupting with “sheker sheker tirchok”, the talk was successful. So, maybe I took Frontier to get those possibility off your mind. Highly recommend to everyone who had non-kosher business thoughts.
