Jet Airways — Basinet seat for infant

Address:

Nagpur, Maharashtra

My Jet Airways PNR : GYYWUY I have booked connecting fllight from Nagpur-Mumbai-Abu Dhabi-Brussels Flight from Jet airways site. When I called for Basinet seat for infant and seat for us accordingly Jet AIrways customer service agent told us Mumbai onward journey provided by Etihad so you shall contact Etihad and gave me PNR (BOCXDB) Number of Etihaad. When I called Etihad customer care they told you need to be present in Mumbai airport 3 hours prior for checkin and its first come first serve basis. I was telling them I have connecting flight from Nagpur. But they didnt listen. Whats the benefits of taking connecting flight if you need to again personally present in first come first serve basis facility. I see there is no co-ordinations between Jet and Etihad when code share service provided and All Hassels goes to Passenger.
