The 10% deal with CR has expired and I just found that Shopback is having 5% cashback for Trip.com
Tracking is quite quick, I just booked a flight and cashback showed up in my account within 5 minutes.
Trip.com is the part of Ctrip.com one of the biggest booking services. I found that their price is in fact the cheapest especially when they don't add any credit card surcharge. You can always check your price on skyscanner to compare but make sure you add other fees and surcharge from other websites to compare.
Their customer service is very good, you can chat with them via Trip.com app.
I don't know when this cashback expires since it is not mentioned on Shopback website. Maybe Shopback rep can confirm the expiry date of this deal?
Just watch out with your personal info with trip.com
I made a hotel booking for Europe last month and provided my mobile number to the booking page which is a new number I just got (that recent circles 80gb deal). The next day I got 2 robo-spam calls in mandrian.
Mate at work translated and said it was some kind of DHL scam.
Cant say 100% was trip.com but no one else had number and I never got robo calls in mandrian before till after trip.com booking
I still book with this mob but use burner email and phone
