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

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

IT issues at Frontier Airlines triggered a brief ground stop at all of the U.S. budget carrier's destinations on Thursday evening, according to an advisory from the U.S. Federal Aviation Administration.

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.

A temporary Ground Stop was issued for all destinations for Frontier Airlines on Thursday, according to the Federal Aviation Authority.

Frontier Airlines is making another offer to merge with bankrupt Spirit Airlines, less than two years after a previous plan fell through.

Frontier Airlines has made another bid for Spirit Airlines, but the offer failed to sway the South Florida-based ULCC as it proceeds through a Chapter 11 restructuring.

Denver-based Frontier Airlines says it’s ready to keep talking after bankrupt Spirit Airlines rejected its offer to merge.

Spirit Airlines rejected a $400 million merger proposal from Frontier this week, saying the offer was financially inadequate and came too late. Spirit Airlines declined an opportunity to merge with rival low-cost airline Frontier on Wednesday.

Frontier and Spirit Airlines will once again try to merge, only months after the Biden administration won a key antitrust court battle to block an attempt by JetBlue to buy Spirit.

Frontier Airlines’ second attempt at acquiring rival Spirit Airlines could impact not only one but two western Pennsylvania airports although the bankrupt air carrier said it preferred to emerge from bankruptcy protection as a standalone carrier.
