I had mbna Alaska card that I closed 4-5 months ago, after applying for mbna 2% cashback card.

I have just applied for mbna Alaska again, and was approved instantly online with a $5k limit. However, the limit on my existing mbna 2% cashback card was reduced by $5k without asking or notifying me. FYI.

I still have the companion voucher from my first mbna Alaska card showing in my Alaska account. What will happen, will I have two vouchers after I activate my new card? If yes, is it possible to use two vouchers on the same flight for 4 passengers?
