Make overbooking of flights illegal

As one of seven people bumped from a flight from Heathrow to Hamburg, I am standing at the ticket desk with the other passengers. Eurowings are only offering single seats on different flights over the next 36 hours. This is woefully inadequate when there is a family of three where the child is only five years old. The practice of speculation that there will be about 5% of passengers failing to arrive so selling extra tickets on the off chance is appalling profiteering and needs to be stopped.
