Pretty much everything was fine with our 40-minute flight itself. The plane was an older A321, but clean and well maintained. Flight was on time. Our only complaint was the same as hundreds of other passengers. They seem to routinely milk passengers for an extra 108K VND for not having middle names entered in their system exactly as appearing on passports. This is the first airline I've ever seen scamming passengers in this manner. It literally took the agent 15 seconds to change my name in the system, but she insisted to charge the "booking change fee". The staff said many, many passengers complain about this racket. It would be exceedingly simple to revise their booking program and include a warning on the booking site about the strictness in requiring the middle name, but they obviously don't want to eliminate this cash cow. Imagine, an extra 108K VND from half of their passengers!! I'd give this airline at least four stars based on everything else, but they get a major "F" for failure to properly warn people on their website and scamming the overcharge!
