Frontier said in a release that it has met with Spirit’s board and executives since it made its proposal this month.

Frontier is making an offer to acquire the beleaguered Spirit Airlines, which filed for bankruptcy in November.

Budget carrier Frontier Airlines announced on Wednesday that it has made another bid for fellow discount carrier Spirit Airlines, which is in bankruptcy, for an undisclosed sum.

Frontier Airlines is attempting for a second time to merge with the now bankrupt Spirit Airlines, which declared bankruptcy late last year as budget airlines struggle.

Rather than accept Frontier’s offer, Spirit said it would stick to its current plan to emerge from Chapter 11 bankruptcy.

Frontier Airlines' attempt to buy fellow budget air carrier Spirit Airlines out of bankruptcy has hit turbulence.

Frontier says a merger would be a better path out of bankruptcy for Spirit, as budget carriers struggle with high costs and competition.
