You should definitely grieve that. As Article 40 states & was quoted earlier, you should not have been waiting for packages off the clock. You weren't just sitting around, you are "engaged in waiting". It is reasonable to ask you to take a break in that time period if they knew the delay would be an hour or more. Every contract has prescribed 1/2 or hour unpaid lunch periods, not 'however long they deem necessary to avoid paying you". They employer should have invoked the language to delay your start time up to 2 hours when they knew the plane was going to be late as they apparently did prior to you starting.
