If you look back into the Etihad posts you'll find 2 such disgruntled people who seemed to have endless amounts of time to negatively comment about Etihad. Only problem was it was discovered neither of them did or had ever worked for Etihad.
To summise watch out for those who may have failed their Etihad assessment and yes the happy few are indeed too busy to usually comment here whilst we are out with our families making the best of our lives here and actually enjoying it.
