Back in 1974, I bought an Airfix 747 kit that had a cracked windshield. I sent the Parts Replacement Request slip back to Airfix and 11 MONTHS later, I received a replacement windshield... that was also cracked!
About two years ago, I noticed that you could request parts through their website. Having acquired a fair number of Airfix kits, I had also found a few parts that were either broken or misssing. I thought it would be a good idea to give Airfix another chance at replacing some parts. I couldn't believe it, but in ONE WEEK, I had received all four parts I requested AND they were packaged such that breakage during shipping would have been impossible. I was VERY impressed and am now a Fiercely Loyal Airfix Fan.
BTW: I recently become interested in Airfix kits as a collector. About three years ago, I purchased a Scottish Aviation Bulldog trainer as an impulse buy just out of curiosity. I was very impressed with what $4.50 got you. From there I started buying more "cheap" Airfix kits, most fairly ancient and reflecting their age. Although a lot of these older kits were in no way up to today's standards, they "felt really comfortable". They took me back to my days as a kid in the '60s & '70s when you could pick up a kit for $.49 and have a whole afternoon of fun. Back then, Airfix kits were also sold under the CraftMaster and MPC brand names. I should also mention that most of the kits made in the '70s & '80s are still pretty good (e.g. S.A. Bulldog, F-84F Thunderstreak, Lockheed U-2).
I had pretty much ignored Airfix kits as a kid because I was more interested in jets than props. As an adult, I'm rediscovering my youth as I collect old Airfix kits packaged in the old boxes and bags. I'm glad that Airfix has continued to produce many of these old kits so that a whole new generation of model builders can experience the simple and inexpensive joys of modeling.
