Tiger airways pay to go home for $1 promo (+ actual example prices)
Terms of the deal are that you've gotta select a round trip, on a valid route for travel between 23/07 and 18/09. The return leg will be shown as $1. If its not then its either sold out or not included in the promo. You have a $9 charge on credit card fees and the return leg must be on a Tuesday or Wednesday. School and public holiday dates are blacked out. If you use a mastercard debit to pay you avoid the $7.50 card charge. There is a booking fee of $17 which is a bit scummy but thats just one of their charges - which again you reportedly avoid if you use the mastercard debit. Infants will cost you $30 and no the mastercard debit rule doesnt apply there.....
Routes with the $1 associated are listed at http://www.tigerairways.com/au/en/real_deals.php
Some actual example ticket prices.
Melbourne - Sydney return $41
Melbourne - Perth return $111.
Sydney - Adelaide return $81.90
Brisbane - Sydney - $72.95 (inc booking fee)
