Awful experience at Trivandrum airport flying with Emirates. This is an international airport and fails to provide a working card machine to take payments which I found unbelievable. The weighing machines at the check in tills show a higher weight than the self weighing scales at the sides of the airport. I wonder if the scales are rigged if I m honest. As a passenger please do check and raise this with staff if you enter any time soon. (I didn t have the chance to)
The security staff as you enter are incredibly dismissive, rude and arrogant for no apparent reason. The staff on the check in tills try to be helpful but when the structure and organization is so poor - this is an onerous task. If you re trying to promote tourism of the country- start by making the airport experience a good one. Complimentary WiFi should be provided at a minimum for two hours if you are trying to lead the way for tourism. I am suggesting this after traveling all over the world - some developing nations of much smaller airports provide a much better service and as a basic- WiFi. I hope someone senior takes this feedback onboard and makes a change for the better.
