Nepal international Airport ranked 3rd in worst airports in 2014, Nepal makes tons of money from Turkish Airlines thru permit fees, surcharges and ground handling. So when Nepal doesnot care a bit abt improving condition in its own airport, why would it ban Turkish Airlines ( a good source of income) which provides worst experience to Nepalesepassengers??? Nepal will never ban Turkish Airlines, the only option is to avoid the airlines, leave bad reviews if u had bad experiences with the airlines.
