මම ඔකෙන්ම තමයි ටිකට් ගන්නෙ. ඔය දාපු ටිකට් එක ආවෙ Air Asia වලින්.
Recently I checked and found that sometimes these guys are more than the airline. As an example I searched from CDG to ZAG and found that Air France was cheaper than any of these online ticketing guys. I booked through AirFrance, no credit card fees or anything added.
Also there are advantages when you book from the Airline even though it might be a bit dearer. I had CMB-SIN-LHR return booked for August 2020 through SQ directly. They refunded me in FULL... Nothing deducted at all immediately after the Covid lockdown. I know for those who booked from Colombo booking agents, to receive the money it took months with admin fees deducted. Also they refunded another ticket which I had with them booked for 2021.
Also at that time I booked LHR-KEF-LHR return (Icelandic Air). I didn't get the money back but they issued be with a voucher valid for the full amount (around 1250 USD for the family) for three years. I used this voucher just a few weeks ago to Visit Iceland from London. Got the flights at the same price.
During these uncertain times I would stick with the airline. Much less hassle.
On anther note LHR is a disaster area. Thousands of lost (or rather misplaced) baggages lying around the carousal areas. Don't know when they get their act right. Many passengers have lost their luggage. In fact when I travelled to Iceland, my London friends told me to leave any baggage with them and take only the carry-on. They said on the average the wait for checked-in baggage is one and a half hours and lucky if you get your bag. Heard that both LHR and CDG are in a complete mess.
