Flew TK to ABJ from BOM (via IST / COO). The agent (Celbi-nas staff) at the BOM-T2 check-in desk for J Class / *A Gold members was the grumpiest I have ever seen. Through checked-in and Lounge invite issued for GVK - Business section. Good flight with nice IFE, ample seating comfort on the B777-300ER and a nice effort on part of Do&Co to match AVML of Indian tastes.
The THY Lounge at IST is one of the best, spread across 2 levels and has more than enough aminities and features to spend time. Shower facility, Mini-Cinema, Gaming Consoles, 9-screen TV station along with plenty of F&B desks and zones spread across the seating area.
The onward connecting flight on the B737-900ER was slightly better than it's bigger sibling, as TK haven't installed individual air vents overhead the seats. Seated at Window, while the sun is blaring outside becomes a bit uncomfortable if the vents aren't focusing on you!
A mini kit with eye shades and ear plugs was distributed to all, on both flights.
Good value for money and the Lounge at IST more than makes up for any flaws if at all.
