Tap Portugal didn't load my bag when I flew LIS-LHR and it was delivered to me the next day.
I complained and they gave me $100 Voucher.
Lot Polish didn't load my bags (2 pax, one bag each) when I flew WAW-TLV, being that I flew in Thursday night, it came in the next flight (Saturday morning) and couldn't be delivered to J'lem until sunday morning.
After pressuring them a lot and asking for 25K LH, they gave me 5K
