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. Frontier Group Holdings Inc., the parent company of Frontier Airlines, said Wednesday that the proposed deal would include newly issued Frontier debt and common stock.

Embattled carrier Spirit Airlines rejected a second merger bid from rival Frontier Group on Wednesday—but the renewed efforts to reach a deal could be a sign of what’s to come for the aviation industry now that Donald Trump is back in the White House.
