I am a frequent traveller on National Express and because of the on going failures I wanted to warn others. For the last six times my wife and I have travled we both paid extra to deser e seats so we can sit together. Everytime we board we mention it to the drivers who are either not aware or don't care. When we board there has been other seated in our seats we paid extra for. The driver is not interested in movi g passengers and just go avout his business leaving us to sit elsewhere and sometimes apart. DO NOT PAY THE EXTRA FOR RESERVING SEATS, THEY DON'T DO IT!
