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.

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.

Spirit, which filed for bankruptcy protection last year, says it has rejected the new Frontier overture but would be open to a higher offer.
