Oceania and Canadian Air review: Airline transportation

Was promised airline ticketing yesterday
No help from Oceania
Want to choose seats on Canadian Air was told need ticket and will be charged about $80 to $90 for assigning seats before arrival at terminal
Also will be charged up to and might exceed $125 for baggage
When signing up with airline included there should be no additional charges
I loved my previous cruising with Oceania
As a result I signed five more passengers with you
This may be our last with Oceania
