Court confirms passengers can claim dating back 6 years
For example, Thomson is telling passengers the period of limitation is 2 years based on the Montreal Convention. Many passengers do not know that, in fact, they can claim for flights dating back 6 years when they depart or arrive in the UK. This is exactly what airlines try to achieve; confusion, in the hopes that passengers give up.
Luckily a British Court put an end to this. The judge ruled in favor of the passenger and decided the 6 years limitation is applicable in the UK.
