In the early days, one might hope that Thomson and other carriers would prefer to let me quietly board another flight and not have a public row about it.
They won't have a public row about it. You are free to elect not to travel. They have fulfilled their end of the contract, and you have chosen to abandon it. They will be happy to sell you another contract but it will be on exactly the same terms in this respect.
This airliner is certified for public transport operations. If that doesn't allay your fears or concerns, or you wont travel in months without an "R" in them, or your horoscope doesn't mesh with your interpretation, that is all Ok. The A320 you get on instead, might decompress at 35,000ft. The B757 may have a smoke event. The B737 might need to divert with a sick passenger. Who knows?
