My friends and I have managed to get 6 first class saver suites to and from Singapore on the one flight.
On the way back we initially only had 4 as 2 had not clear cleared the waitlist (they had back up confirmed business saver fares). We all checked in together at the First class check in...
Just a reminder, even though most of these offers say "excludes gift card purchases" I have never found that to be the case.
I bought $300 worth of Harvey Norman giftcards online and have already received the $50 credit confirmation email from Amex.
