The Swefly 767 was positioning in on Sunday. Nothing more than that. There is no inbound flight this Monday. The 767 will perform the outbound flight to Sweden and, I guess, on to Lahore.
Saturday's 757 was full. Given this encouraging start I think it would be reasonable to see the 767 on most of the LBA flights with an increased frequency. Don't know how this will affect the Luton leg.
In the longer term, it may make sense to go 'direct' to Lahore with a refuelling stop only, say in Larnaca or Muscat, without picking up pax from other airports. This is providing the crewing issues from Sweden can be satisfactorily addressed.
PIA must be PIA'd off !
