totally agree with nishantvshah.
the star raking is just for the name or the sake of it.
i have worked for one & was surprised to see how passengers being treated. finally i quit, coz i couldn't stand it or the attitude of the staff. as living beings, every one likes to be treated nice, oh! but only if the staff understands that point...
points which every employee in an airline should understand is that,

1, they get paid out of the revenue brought in by the customers.
2, every one has their own personal ups & downs, yet it is the responsibility of the employee to select the perfect job for them selves, (if they cannot handle the pressure they should not take up the job to make other peoples lives missarable) they should not at any cost show attitude to passengers, employees problems are not problems of passengers, regardless of what class a pax would travel, they have paid for the service & has done their part, it is the sole responsibility of the handling staff to give the best out of them.
3, regardless of how much CEO's & executives runs behind strategies for a better business when the implemented ones arent being followed!!
