This 'letter' may well be true and have actually been sent. It certainly seems to encapsulate much of what is felt in the airline biz. However, such 'letters' have been written in almost all areas of business and corporate life. I recall examples of resignation letters doing the rounds 20 years ago. What is important is not whether this one is true or not - but that it has sparked an immediate recognition. It wil be interesting to see the thread develop.
To Baywatcher, sorry if it hurts for me to cast doubt on the authenticity but that's my view this morning.
