Aug 12 (Reuters) - Spirit Airlines has warned

of going-concern doubts, just months after emerging from

bankruptcy as weak domestic demand and dwindling cash reserves

strain its operations.

Adverse market conditions such as elevated domestic capacity

and weak demand for leisure travel in the second quarter has

resulted in a tough pricing environment for airline, it said in

its quarterly report on Monday.

The company expects these pressures to persist through the

rest of the year, adding to operational uncertainty. Last month,

Spirit said it would furlough about 270 pilots, while demoting

another 140, to conserve cash.

The Florida-based airline, known for its bright yellow

livery, had filed for bankruptcy protection last November, after

years of losses, failed merger attempts and heavy debt.

It was the first major U.S. carrier to file for Chapter 11

since 2011. It emerged from bankruptcy in March after a court

approved restructuring backed by its creditors.

Uncertainty stemming from President Donald Trump's sweeping

tariffs and budget cuts have prompted travelers to curb

spending and reassess plans.

The airline said on Monday that its credit-card processor

has asked it to set aside more funds as collateral or risk

losing its contract, which is set to expire on Dec. 31.

To address the concerns, Spirit said it plans to bolster

liquidity by selling or monetizing aircraft and real estate and

shedding excess airport gate capacity.

Uncertainty over meeting minimum liquidity covenants and the

outcome of talks with stakeholders have raised substantial doubt

about the company's ability to continue as a going concern over

the next 12 months, it said.
