I am flying DYU-IST-LHR
As of this moment, the flight from DYU is delayed by 80 mins, therefore considering I have a 1.5 hour connection, I am missing it.
I checked online and there are no available flights for that day in IST to LHR, at least no none stops that I see. However there are 2 BA flights, one of which still has econ seats available, although both have 2 buisiness class seats available.
Basically, I need to know what is going to happen, if the plane doesnt catch up and I do miss my connection, will I get put on the BA flights? Or will I be forced to wait until Tuesday night, the next available flight I see to Heathrow.
Is there any way they put me on a connecting flight to LHR, routed through some other country?
Also, this would be a pleasant surprise, would I be able to claim any kind of compensation or even better would be being upgraded to business class? Is that an option.

Thank you for your replies,
