Surely, if it worked, premium seats would start filling up with honeymooning couples and cabin staff would have to start questioning a decade of declining marriage rates. Looking at the $900 difference in cabin prices to Bali, the cost of a $240 wedding licence and a little forward planning seems like incredibly good value.
However, if you are hoping to rock up to the check-in desk and bluff about your nuptials, you've got some nerve. What are you going to do if they ask to see your marriage certificate?
This whole debate leads on to another point - in some destinations, travelling as an unmarried couple can cause big problems. Conservative or devoutly religious countries can sometimes have strict rules on who can and can't share hotel rooms.
Indian hotels in the popular honeymoon beach states of Tamil Nadu and Kerala require passports for check-in, which can be a problem in more conservative areas. Last year, district officials raided an unfortunate "unmarried couple" in Chennai who had "occupied a room and consumed liquor". Shock horror.
Most holiday destinations are "accustomed" to cohabiting couples, but you shouldn't rely on people to turn a blind eye. Parts of Indonesia, in particular, have very different views on unmarried travellers' sleeping arrangements.
After the country promised to crack down on extramarital sex last year, you only need look to the headlines about the proposed "Bali bonk ban" to see how unscrupulous operators might look to exploit or extort holidaying couples. At the time the Centre for Indonesian Law in Melbourne reassured travellers that Indonesia was "awash with laws that are never enforced", but also aknowledged these awkward grey areas could leave tourists exposed to extortion by those fishing for bribes.
Lying about being on your nuptials seems like inviting trouble.
It's best not to provoke too much scrutiny if you don't want to spend your fake honeymoon on opposite sides of a hotel.
