All checked in luggages didn’t arrived with us. But 2 flights after us. Mind you the flight wasn’t full at all and most people don’t have much to check in. No apologies or explanation why it happened. Nothing! Told us they will call us when it arrives. Nope no calls just us coming back 2 hours later to find out when it came. They called the next day to ask if we have it. Are you kidding me?! No apologies or any compensation. They said they will compensate but nope. A 2k miles voucher we will never use since we don’t want to be disappointed anymore. So disappointed and upset.
