I use on-line booking.
Unless it was for overseas, that's a face to face booking then.
I don't have any one company, I just look
for the right deal....for the right day and time.
It has always worked out fine.
We are 5, so tend to only book flights on sale, and build the holiday after that. Recently, we got 5 return tickets to Singapore for $1500 (total) on Scoot, but as we'd recently been to Singapore, only had 3 days there and the rest of the time was in Malaysia (Tioman and LEGOLAND). We've done the same again, and while we only have the flights to Singapore, the plan is to go to Vietnam.
My husband uses his 'staff travel', online. because as he was with the flight company for 33 years, he gets the discounts for 33 years, from the date he took his redundancy!, but he reckons he's be dead before the time is up! I could use his discount for another 5 years, but I'm sure I won't feel like flying in my 90's, by then. Also i have no idea how he makes the bookings on line anyway.
