Air India — Overall service

I have flown Air India all my life from Heathrow to Delhi, mostly twice a year. Since privatisation, the services have gone from bad to worse.
The cost cutting is evident almost everywhere but the prices charged are MORE than most excellent international carriers! Unacceptable!
The carriers are ancient reducing leasing costs.
Almost most of the screens don’t work which on a long haul flight is unacceptable.
AC kept at a level where it was clammy, another way of cutting cost.
No menus circulated as seen on other flights - the air steward asks - veg or non-veg without saying what do they contain. Cost cutting again.
No salt and pepper - cost cutting.
Single ply napkins - cost cutting.
Same corn salad in both meals - economies of scale and cost cutting again.
Musty horrible smell both whilst flying in and when flying out.
I could go on and on ……
Do I get part of the flight refunded because it was certainly not of the level of other international carriers!
I am going to post this on Twitter and write to Star Alliance and IATA to look into this shambolic state of affairs!
