Connecting flight time Stockholm
I have booked a non-amendable ticket from Stockholm (ARN) to Miami (MIA), via London (LHR). I no longer plan to go to Stockholm and will actually be in London.
The most convenient flight for me from LHR to ARN only allows a 45 minute transit time before I return to LHR.
The ARN to LHR aircraft will be the same as the one used to travel LHR to ARN, i.e. if I am delayed leaving London, the inbound will also be delayed. It is BA.
Will the fact I am using the same aircraft to return mean I am safe and can make the 45 minute transit? Will I have to go through security? I will have no luggage.
