4. (1987) You need to fly from Seoul, South Korea to Guayaquil, Ecuador. Unfortunately, there are no easy ways to do so. At least you won’t have to connect through Tokyo. Your itinerary will involve three nonstop flights, each operated by a different airline, with each airline operating an aircraft built by a different manufacturer. You know the drill by now. Please provide all the relevant information.
Dusting this one off for a new day:I will hold off on a new guess for #3 until we get a ruling on the KE vs SEL guess posted upthread
UA SEL-SFO L15
PA SFO-MIA 747
EU MIA-GYE D10
An excellent guess, and a most plausible possibility. Unfortunately, per the schedule used to reference this question, these flights and itinerary won't work. It's kinda surprising that Miami's not in there, and indeed it could have been, but then the three different a/c manufacturers parameters could have been met.
However, you have identified the three aircraft involved in this itinerary, and the 747 is operated by PA.
Please, guess again.
A PA 747 not touching MIA and by 1987 the Pacific division was gone to UA. Perhaps this itinerary went west as opposed to east. Thinking something like:
LH SEL-FRA D10
PA FRA-JFK 747
Faucett JFK-GYE L15 (kind of grasping at straws here but maybe a Peruvian carrier would stop in Ecuador on the way to Lima?)
