Aug 22 (Reuters) - Spirit Airlines is weighing

a range of strategic options after its recent financial

restructuring failed to secure a sustainable future for the

budget carrier, the Wall Street Journal reported on Friday,

citing people familiar with the matter.

The airline has enlisted financial adviser PJT Partners as

it navigates a cash crunch and is also working with consulting

firms FTI and Seabury Airline Strategy Group, according to the

report.
