Downgrade compensation
My wife and kids were flying AC HNL-YVR last week. I upgraded them all by LMU the day before to business. As they were boarding with group 1, boarding passes in hand, they were paged to the podium and informed they were being downgraded due to an overbooking situation. They were given economy boarding passes and told to contact AC customer service for refund of the LMU. No compensation was offered. This was a red-eye flight, so the business seats were more important than usual.
Is a simple refund of the LMU really all that will be given? Or should actual compensation be given? If it matters two of the family are E25K.
