It matters heaps.
I am looking at 20,575THB airfare. Yesterday it was ~AUD719 and today it is ~AUD694. Tomorrow it could be ~AUD669.
I also need to book another airfare ~4,740THB.
I also need to book an airfare which is ~1,090SG. Yesterday it was ~AUD956 and today it is ~AUD936. Tomorrow it could be ~AUD916.
It may not sound like a lot to you but it is a lot to me. I am going to Thailand in September/October, December/January and planning to go in April and July.
I am trying to squeeze another trip to Thailand in February for my 50th birthday.
