As the 737 MAX 7 you see here begins flight testing, we’re delighted that our 737 MAX 8 customers continue to take full advantage of the airplane's capabilities. 💪 We also just celebrated the first customer delivery of the 737 MAX 9 and its entry into passenger service. We can’t wait to see how airlines continue to show off the 737 MAX family's incredible range and flexibility! #737MAX #boeing #aviation #airplane #avgeek #thinkmax
