Just read a report on Air India' flight BOM EWR was cancelled on Fiday . Pax were boarded on time. It took four hours to declare that aircraft had gone technical / mechanical. There were no progress reports from crew. The crew disappeared before pax were off loaded!
Pax did not see any AI staff for hours. We're stuck in secure area airside.

Question is : What are Star A protocol a and or contingency plan recommendations ? Does the Alliance compile such info on members ?
I have not flown AI in decades. Thought with the Alliance membership pax handling would have improved. No luck. So still not on my list of airlines to fly.
