We flew to Hawaii this February with Westjet and they put us in their 737 Max 8 aircraft. Enroute to Kona, we experienced what I thought at the time was severe turbulence but after learning of the Lion Air and Ethiopian Airlines crashes, I now believe that this bone-jarring, terrifying experience was due to the seriously flawed design of Westjet's planes. Upon learning of our horrible flight, family members in aviation told me that had they known we were flying on the 737 Max 8 they would have warned us not to do it as this plane has very bad aerodynamics that make it extremely unstable at high angles of attack. To make matters worse, as many may know by now, Boeing tried to compensate for bad design with the MCAS software patch, with disastrous results. After learning of the Ethiopian Airlines tragedy less than a month after we returned from our trip, and the subsequent grounding of all 737 Max 8s, I was furious that Westjet put its passengers in such a dangerous situation just to protect their bottom line. I wrote their CEO Edward Sims in early April and asked him for a full refund of our tickets as well as several questions about whether Boeing had made Westjet aware of the MCAS software patch before they bought their planes, and if so, did Westjet train its pilots to deal with the MCAS software patch. I also asked if Westjet was aware that several pilots who experienced serious problems with the 737 Max 8s MCAS filed complaints with Nasa soon after the Lion Air crash. Two months later, I still have not received any compensation nor have I gotten any answers from Westjet about how and why they put their passengers in such a dangerous aircraft. Any help with this would be much appreciated!
