I booked the flights back in October. At the time when I booked,on line, I was given a confirmation number and it said to print the ticket. I dont have a printer so I saved the page into my favourites intending to put it on a stick and get my friend to print it. I did this for all 3 flights and when I came to get the info they had timed out and no info available. I was going to email Tiger airways but they have no email, you have to write to them in Singapore. I did that and they say to wait for at least 21 days for an answer. That was 5 months ago and still no answer. Yesterday I had a brain wave and checked out my bank statement and the payments had the confirmations on them so I was able to get my friend to print the tickets.
Vietnam does not have Visa at the border so it has to be arranged before you go. I could have got one from the embassy in Canberra, by sending passport. The best way is pre arranged visa. I used "My Vietnam Visa" and they arrange the visa and send an approval letter. This is enough to get me on the plane and I get stamp when I arrive in Vietnam.
The plan is to fly to Saigon spend a week there and the Mekong delta, a week travel north through Danang, Hue and Hoi an, then cross into Laos for a week and exit into the north of Vietnam for a week in the mountains at Sapa and down to Hanoi. Fly from Hanoi to Singapore for 3 days before I come home.
I will post again when I get there.

Lucky I got the itinerary cos when I got to Perth airport they wanted it with my passport and visa. I asked the guy checking me in and he said they could have refused me to travel without it. Having said that, they did not ask for it in Singapore. Because I had no check in luggage they check weighed my hand luggage and let me off with point 6 of a Kg overweight.
Singapore airport in like all the low cost airports in Asia. you have to walk down the steps and across the tarmac. I arrived at 3am and it was beautiful and warm and that familiar smell of Asia, it was great.
The visa was pretty slack. I only half filled out the form and they handed over the visa. It only took about 10 min and very painless. I changed $100 into 2.1 million dong...Im struggling with the huge numbers. I was just quoted 40,000 for a hat.. thats $2 so Im go buy it. Its a keeper.
The taxi crooks at the airport thought I was a newbie and were quoting $20 to $25 for a taxi to my hotel. I got it for $7 just by walking away and negotiating with a reasonable guy.
