Ive been given 2 $400 TCO vouchers from Hawaiian as a 'We are sorry we stuffed you around' gift.... They are for Hawaiian air travel only.... My question is this ... Can I use them when booking with Orbitz, Travel.com.au etc... or do I have to wait for a 'Hawaiian Airlines' fare...????

Over here the likes of zuji, travel.com etc always have lower fares then the actual airlines... I hoping to go back to beautiful Hawaii in March... But the Hawaiian website has fares at $1700 pp V $700 on Travel.com for the exact same flights...
