I was a Boeing lifer. (27, 37, 57, 67, 77) and came to the Bus left seat about 14 years ago. (I didn’t want to go back to guppy left seat) I have never regretted the decision. The Bus ‘thinks’ different. I ram dumped everything Boeing and accepted fifi for who she is. It took about 3 months until I was comfortable in the seat.
I’d rather fly 2-3 leg Airbus domestic vs Boeing international so I’ll retire off fifi in a couple years. Nice problem to have though, trying to decide whether to be a 73 or Airbus Captain.
