Beware of airport scams everyone! We were booked economy class as part of a group. However we were told by airport staff that for $US60 we could upgrade to Business for the flight to KL as business was empty according to them. Which we did. We got the extra baggage allowance and we even had use of the Business class lounge. When we got on board the boarding passs had us all in economy. We stuck to our guns for as long as we could but had to accept Economy class with Uzbekistan Airways after the police became involved. Possibly one of the most corrupt places we have been to. Pity as the country is well worth a visit.
