Worst Ground Staff Service
Check in on flight from JFK to Singapore, The check in staff on JFK seems like a trainee and so careless. while checking in the staff work very slow while giggling with other colleague, the boarding pass and luggage tag was printed on the other counter ( this could be the start of the nightmare since it increase chance of human error). (especially ground staff named RAHIM using foul language and having bad attitude towards customer) When Arriving at the destination, Lost a checked luggage and the staff could not locate/trace where is the luggage. All customer service online & offline only use template reply like automatic reply which frustrating.
