| My flight was from Chennai to Miami on Jan 6, 2019 Chennai-Delhi-Amsterdam on Jet Airways 831/234 . Amsterdam -Miami on KLM 627. Ticketing done by Delta, but operated by Jet Airways and KLM. On Jan 6th during check in at the airport counter at 5 pm, the agent said the Jet Airways connection flight #234 from Delhi to Amsterdam was cancelled. There was no email or phone message regarding cancellation. It took them almost 2 hrs to reroute via Chennai-Paris on Jet Airways 128, and Paris-Miami on Air France 090. Jet air ways 128 is at 1.45 am on Jan 7th. Service, attitude of the Jet Airways staff was horrible. They did not seem to care. one would say some thing and walk away, saying some one else would help find the rerouting. They were going away on breaks. No one seemed sincere or interested in doing their job. Rerouted as Chennai- Paris on JA 128, Paris-Miami on AF 090.Connection time 2 hrs Later on, when i check on line it shows the flight 234 flew as scheduled. Its obvious the ticketing staff at the counter lied. I can't figure out why they had to lie and made me stand anxiously for 2 hrs. Another problem is- even though the bags are checked to the final destination, Jet Airways would not issue the boarding pass for the Paris-Miami segment, asking me to see a help desk at Paris airport. This flight 128 from Chennai to Paris went in late, and there was no help desk on arrival. I had to run to International transfer area, security and wait in line to get on a shuttle bus to get to the Air France Terminal. Business class boarding door was closed by the time I got there. I was probably the last person to board. Ticketing done on code sharing problem- Delta gives a confirmation number which does not work on Jet Airways, KLM or Air France. It took me a while calling Delta and my travel agent to figure out the PNR number of my reservation on Jet Airways. Both said that I have to get the reservation confirmation numbers from the other party, Delta says to get the PNR for JA from the travel agent. Travel agent says to get it from Delta. Finally Delta gave me a PNR number which did not work. So, I had to call Delta again, wait listening to music for over 30 mins, and was given a different PNR number, which worked to open my trip on Jet Airways. Despite entering the correct PNR number, Jet Airways does not let you select your seat.
