Thank you for your question.
There is no doubt that common sense dictates that, if one passenger is eligible for compensation, then others on the same plane should be as well. What we have actually been hearing is quite the opposite. People sitting next to each other, possibly a husband and wife, both file a claim and one receives compensation and the other receives a rejection citing the various excuses that are provided under the APPR.
What we also need to bear in mind though is that the compensation amount is based on delay at the destination. If you have two passengers travelling to different destinations, the delay of the given flight or the cancellation of the given flight can affect their arrival time at their final destination differently.
Eligibility can be determined on a flight basis, but the actual amount of compensation may vary based on a passenger's travel plans.
