The Alaska Airline Gold account is NOT a Visa card, so you would not change over to the Platinum Plu

The rewards are a generous traveling nurse agencies 3 miles for every qualifying net retail dollar in purchases of Alaska Airlines/Horizon Air tickets and vacation traveling nurse agencies packages and 1 mile per $1 spent on qualifying traveling nurse agencies net retail purchases elsewhere.
Interested in changing my existing Alaska Airline Gold account over to Platinum Plus. First question, does this card still have the yearly companion reward, and Second, how is one to accomplish the change over?
The Alaska Airline Gold account is NOT a Visa card, so you would not change over to the Platinum Plus Visa card, but have it in addition to your current Gold Mileage card: you would have two separate Alaska traveling nurse agencies Airlines accounts a Gold Mileage Account from Alaska Airlines and a Platinum Visa card administered by Bank of America. Call 1-800-654-5669 to find out how it works. The Alaska Airline Mileage link says Add an Alaska Airlines Visa Signature® Card and we'll give you another 25,000 miles, plus 1,000 bonus miles every time you use your card to buy tickets at alaskaair.com.
I currently have a Hawaiian Airlines Visa card with B of A. Can my local B of A bank change traveling nurse agencies this account to an Alaska Airline Visa card and retain current charge limits? I pay off my balances monthly.
No because each credit account is a separate entity like you cannot change one person to become another: they are individuals. B of A acts like a parent who runs a family of accounts, with each having their unique identity. Sorry, but you have to create a new Alaska Airline Visa Account from scratch with no support from your existing Hawaiian Airlines Visa card. Do NOT close your Hawaiian Airlines Visa card because having a spotless record with it helps your credit traveling nurse agencies score.
