One hour connection or 7 hours connection in CGK
Hello, I am new here.
I plan to booking on Star Alliance of Thai Airways and Singapore from BKK to SIN via CGK in mid-Jan 2019. I use my mileage to upgrade on both airlines.
TG B787 to CGK from BKK and SQ A359 to SIN (7 hours connection) from CGK
or
TG B777 to CGK and SQ A359 to SIN (one hour connection).
which one the connection flights are best?
Do you understand me?
