One of the worst services I've experienced. I'm never booking through them again. I had booked my flight from Lahore to Chicago, round trip. Once I was in the USA, I had a change of plan and wanted my return flight to be changed: wanted to fly out from New York, this was requested over 10 days in advance to my departure date. After speaking to them, they quoted me an amount that will need to be paid for this change request, I agreed to pay. They then said a representative of theirs will call in 10 minutes to generate payment details. I NEVER RECEIVED THAT CALL. Then following days I kept calling them everyday, and explaining my situation to a new representative each time, each time they said its a system error and I will be called in further 24 hours with update. GUESS WHAT? They never called. After a week of chasing them around constantly nothing was happening, by this time I was alreeady in New york and I didn't know if I have to fly back to Chicago to catch my flight back from from there. Imagine being on you vacation and being in a complete state of stress and panic due to poor customer support. The time difference issue was the worst, because they were not availbale during the day hours US time. The flight from New York was on Friday night, and it was only on Wednesday night time that they called me constantly after midnight to get this process finally intiated - I was up all night just to get this done as they have 10 hoops to jump from just for a simple change. And guess what? The amount that they quoted to me a week ago (which I agreed to pay) was no longer valid, and now they wanted ME to pay more because the fair difference had increased since the flight was just 2/3 days away. PATHETIC. I can't stress enough how much dismofort and mental fatigue this experience has caused me. PLEASE AVOID BOOKING FROM THEM.
