N829DN, one of Delta’s Boeing 737-900ERs, throws it all out on landing at Baltimore-Washington. Delta has 130 -900ERs in its fleet with an average age of only three years- the first -900ER was delivered to Delta in September 2013 (N801DZ) and the 130th one being delivered in June 2019 (N930DZ). This particular aircraft was delivered in October 2017. I was surprised that Delta had so many 900ERs, I assumed they had more -800s, but what I have on hand indicates the airline has 77 -800s and 11 -700s. #Avgeek #aviation #aircraft #planeporn #KBWI #BWI #Baltimore #Maryland #airport #planespotting #instaplane #instagramaviation #Boeing #737 #Delta #DeltaAirlines #N829DN #splendid_transport #instaaviation #aviationlovers #aviationphotography #flight #AvGeeksAero #AvgeekSchoolofKnowledge #AvGeekNation #TeamAvGeek (at BWI Thurgood Marshall Airport (BWI)) https://www.instagram.com/p/B1h9fxIBN3B/?igshid=xgcx922wj923
