I have flown several times with Belavia from Moscow and London to Minsk and have been impressed on every occasion. They might not be cheap from London to Minsk but they are very competitive from Moscow to Minsk. Even better if you fly on their brand new Embraer aircraft which are going to replace the aged Boeing 737s. The staff are very courteous and efficient on every flight sweets are given before take-off and usually before landing food isn't fantastic but neither is easyJet's or BA's. I have flown with Western European airlines into Minsk and the prices are sometimes cheaper if there is a sale on otherwise Belavia offers good value for money Vs. time and hassle avoided from London Gatwick. From Moscow (DME) Belavia code-share with S7 so you will always fly Belavia from DME to MSQ.
