I recently travelled through Singapore airport. This was not a pleasant experience and I would like to warn other travellers.
I travel extensively and this year have been through airports in Europe, USA and Middle East. As every passenger knows you cannot take liquids into the departure lounge, however once in the lounge you are free to buy liquids and take them on the plane.
We were flying from Singapore to Riyadh which is a 10hour flight. On our outbound flight the drinks service onboard was non existant. So that we didn't get caught out again we puchased 4 bottles of water from Starbucks in the departure lounge.
At the gate we were rudely told that we could not take liquids on the plane and that we had to dispose of it. The airport staff would not reason and were extremely abrupt.
When questioning with the reasoning we were just informed it was the rules, however they would let us take through the empty bottles and fill them from the water fountain in the gate. This is illogical and makes absolutely no sense.
I was so disgusted that I wrote to Singapore airport. When they did finally answer their reasoning was that they were following the ICAO rules imposed on all airports post 9/11. It seems to me that the airprot has completly misinterpretted the rules and taken them to the extreme. Not even the USA stops you carrying liquids onto a plane. Whatsmore Singapore airport terminal 1 didn't stop us taking water.
Firstly if you can avoid Singapore airport, and secondly do not buy anything in duty free.
