I work for an airline as their Route Network Planning Manager and I can assure you that in spite of PIA having 70% S/F on its GLA flights, they were not profitable one bit. Please also note that Emirates's flights to GLA are not profitable as well at a "net profit" level. They are profitable at an operational profit level only!
Yes a direct flight might be well received but the volume is not there to warrant year round PIA A310 service on the GLA-LHE route at a decent yield.
Lastly, with regards to your point that "people will always chose a direct flight over a connection", can you please then justify why PIA suspended Houston and now once again Chicago? Also can you explain why PIA no longer operates to Athens, Rome along with being only 3 weekly to JFK. Direct flight or no direct flight, what matters most in this day and age for the ethnic VFR passenger is # 1 price, # 2 schedule flexibility, # 3 baggage allowance and # 4 product reliability !
You might very well work for an airline but unless you work for Emirates as there Route Network Planning Manager then you are not going to have access to this type of information. Are you the Network Planning Manager for Emirates?
Emirates are going twice daily from Glasgow and are introducing a first class cabin on the flight. Business class is always full as it is. Profit, profit, profit!
With regards to PIA and how you say their GLA-LHE route was “not profitable one bit”. Firstly, what is your source for this? You’re claiming to have inside, private business sensitive information from two different companies. So are you the Route Network Planning Manager for Emirates or PIA?
Secondly; you state the GLA-LHE route was “not profitable one bit”. Are any of PIA’s routes?!
