Thankyou for your replies,
The reason I wish to start a claim so late is purely on the grounds that because of recent court judgements I was approached by a specialist claim company. I recollect experiencing delays on both legs of the holiday, 6 hours on the outward trip, 15 hours on the return trip. We were given, at the time, a printed flysheet about the delays to claim off our holiday insurance.
I primarily take out travel insurance for medical & repatriation cover, not to provide Thompson Airways with a get out position.Thompson Airways was not very helpful at all in the situation.
Maybe the recent court judgements will put up the ticket price, so be it, airlines must take their responsibilities seriously.
