About 9 months ago, I booked a flight for my family of 4 going from YEG to PVR for December 27. Some months later I got email saying there was an itinerary change. Flight number changed and flight time changed by 10 minutes. For whatever reason, Delta had rebooked our ticket on Alaska airlines.
Fast forward to December 27th, we all wake up at 3 am and make it to airport 2+ hours before flight time. When we get to Delta counter, the lady tells us that she can't find our reservations. When I show her the printout from Delta website, she indicates its operated by Alaska. Anyways, we manage to get Alaska boarding passes and go through security never thinking anything was amiss. Then when it time to board, we are told that flight is overbooked and they have to find us another flight. Here are the issues:
- Alaska air never told us flight was overbooked ( rumour has it there was an equipment change due to mechanical issue and this resulted in overbooking by 6)
- made NO boarding announcements (people just lined up)
- Never asked for volunteers
- they rebooked us with having to overnight in Calgary and then arrive in PVR next day.
- we lost a day of vacation and prepaid hotel room.

What should we expect for compensation?
(Thanks in advance)
