Firstly, I am not posting to defend the actions or inactions of Phuket Airlines – I don’t know enough about it.
Second, imho, emotive and inaccurate language like "flying coffins" is unhelpful and should be confined to the tabloids. The balance of probability would suggest that flying with Phuket Airlines is/was safer than the car journey most of the passengers took to get to the airport.
Ok, it’s a rumour network, but isn’t it’s also supposed to be professional…
