Thanks for clearing that up, as I didn't really understand how all this worked before.behramjee wrote:
EK are not for a long time reducing their KHI 4 daily frequencies. EK is more expensive for interlining because they have earned that right to be due to them offering better frequencies which results in better flexibility + good inflight product. Airlines that still interline from PAK to DXB on EK are LH, KQ, ET, BA, KLM, AF and VS. A lot of these airlines too have interline agreements with PIA and Airblue on the PAK-UAE sector and as a result charge lower fares if those airlines are chosen for travel between PAK and DXB.

I'd always though this too. It makes me wonder why EK604 is usually operated by a 3 class A330 (which has the least seats of any EK aircraft save the A310 and maybe A345)behramjee wrote:
The most popular flight for the EU airlines for interline purposes on the KHI-DXB-KHI route was the late night EK flight which departed KHI at 2200 and the one that flew back at 0130 from DXB. Even today if you are a normal pax flying on those 2 flights, you pay a RS 1-2000 premium since that flight is loaded with 6th freedom pax flying onwards via DXB to Europe and North America on either EK or another airline.
