Frontier Airlines and Spirit Airlines have discussed a merger yet again, but Spirit rejected the bid in order to pursue a plan to exit bankruptcy on its own. Frontier confirmed the latest merger discussion in a news release on Wednesday,

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

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.
