Be aware about buying tickets and its T&Cs...there may be a big surprise when you want to change ticket due to unforeseen situation!
I recently booked a flight ticket via cheaptickets from Singapore to Calcutta return. Paid about SGD 742. Later for an emergency I wanted to change by return date from 31st Dec to 21st Dec. I went to the platform portal that allows one to manage ticket changes. It then led me to a chat agent. He informed that I will need to pay SGD 26 for Airline Changes + SGD 138 for admin fee + airline current price difference. It was all okay until this. Then the agent returned saying the change few is SGD 892. I checked online for a new one way ticket which was SGD 381. The agent could not help me further as probably how cheaptickets arrangement work! I then bought a new one way ticket at SGD 381 directly with the airline and left my original ticket with cheaptickets unaltered. I will be careful about buying tickets next via agent portal!
