I have an upcoming trip and looks like the most practical option is for me to take TG from one of those locations. In the case of the LHR and FRA flights, it would be the early departure not the late ones. It looks like they are all served by 777 aircraft, any real difference in one route versus the other with regards to service or aircraft? I was underwhelmed by my last trip via TG but practicality might just win the day on this trip.
