Prospectus Summary
Key Operating Statistics and Metrics, page 17

2.       We note from your response to prior comment 10 that you believe that
"presenting certain
         operating statistics and metrics for prior fiscal periods is useful
additional information for
         investors in evaluating the development of the Company's business." In
this regard, it
         appears that you view the financial information for the fiscal year
ended December 31,
         2017 to be material to an investor's understanding. Based on this
position, it is unclear
         why you believe it is appropriate to provide 2017 financial metrics
without the relevant
         financial statements and selected financial data.
3.       We note from your response to prior comment 14 that you believe that
"presenting all
         operating metrics for the twelve months ended December 31, 2018
provides the most
         meaningful information for investors by providing a basis for
comparing the metrics to
         other annual periods presented as well as other airlines." As such,
you have continued to
         present CASM and CASM related non-GAAP financial measures on a
combined basis.
         However, we continue to believe that it is not appropriate to merely
combine financial
         information for predecessor and successor periods. Please submit an
analysis to support
         your belief that the acquisition accounting adjustments did not have a
material impact on
         CASM and related CASM non-GAAP financial measures in the Predecessor
2018 period.
         In the alternative, remove all instances of disclosure where you have
combined financial
         information for predecessor and successor periods.

Special Items, net, page 80

5.       We note the Special Items, net expense for the Interim Successor 2019
period includes a
         charge of $7.6 million related to contractual obligations for retired
technology, offset by
         $1.2 million of proceeds from the sale of unused airport slot rights.
Please expand the
         disclosure of each of these items to further clarify their nature and
why they are
         classified as Special Items.
Non-GAAP Financial Measures, page 81

6.       We note you present a non-GAAP operating measure titled Adjusted
EBITDAR that is
         exclusive of aircraft rent. Aircraft rent appears to be a normal,
recurring, cash operating
         expense necessary to operate your business. Accordingly, this
exclusion does not appear
         to comply with Question 100.01 of the updated Non-GAAP Compliance and

         Interpretations. Please revise your computation accordingly.
7.       We note you have not specifically identified CASM ex and Adjusted CASM
as non-
         GAAP financial measures even though you have reconciled CASM to CASM
ex and
         Adjusted CASM on page 18. Please expand the disclosure under this
heading to clearly
         identify these metrics as non-GAAP financial measures and provide all
         required by Regulation S-K, Item 10(e). Additionally, expand the
tabular reconciliation to
         include dollar amounts, as was previously shown on page 75 in the
initial submission
         dated December 19, 2019.
Off Balance Sheet Arrangements
Fuel Consortia, page 91

8.       We note from your response to prior comment 16 that you entered into
fuel consortia
         agreements during 2019 that are legal entities which you have
determined are variable
         interest entities ("VIEs") under the guidance in ASC 810-10-15. We
further note your
         conclusion that you are a nonprimary beneficiary holder of a variable
interest in these
         VIEs because you are one of multiple members in the VIE and each
member "has no
         special power or voting rights and is not able to direct the
operations of the consortia."
         Expand on your response and tell us how you analyzed the applicability
of ASC 810-10-
         25-38A(b) to support your conclusion that you are a nonprimary
beneficiary. With a view
         towards enhanced disclosure, provide the footnote disclosures
contemplated by ASC 810-
         10-50-2AA and ASC 810-10-50-4 as it relates to nonprimary beneficiary
holders of
         variable interests. In the alternative, explain to us why these
disclosures are not required.
Executive Compensation, page 127

9.       Please provide the disclosure required by Item 402 of Regulation S-K
for John Spanjers,
         or tell us why such disclosure is not required. In that regard, we
note your prior disclosure
         that Mr. Spanjers served as your chief operating officer until his
retirement that was
         effective in July 2019. Refer to Item 402(m)(2)(iii).
Director Compensation, page 138

10.      Please provide a narrative description of any material factors
necessary to an
         understanding of the director compensation disclosed in the table on
page 138. Refer to
         Item 402(r)(3) of Regulation S-K.

as the "Right of First
         Notice" set forth in Exhibit A to the warrant agreement.

Note 3. Revenue, page F-40

12.   As stated in ASC 606-10-50-1, the objective of the disclosure
requirements in Topic 606
      is for an entity to disclose sufficient information to enable users of
financial statements to
      understand the nature, amount, timing and uncertainty of revenue and cash
flows arising
      from contract with customers. As such, it appears the disclosure of your
accounting for
      certain revenue types in this footnote is incomplete without referring to
      made within your Critical Accounting Policies beginning on page 91.
Revise your
      footnote disclosure to ensure it is a complete discussion of your revenue
accounting to
      meet the requirements of ASC 606-10-50-1.
13.   We note your disclosure that "Revenue is primarily recognized when the
      obligation to the customer is satisfied, which is primarily when travel
is provided." Please
      explain your basis for using the term "primarily" in this context.
14.   Tell us how you considered accounting for access to your customer list
and/or use of your
      brand as a separate performance obligation of the co-branded credit card
        You may contact Jennifer O'Brien, Staff Accountant, at (202) 551-3721,
or Shannon
Buskirk, Staff Accountant, at (202) 551-3717 if you have questions regarding
comments on the
financial statements and related matters. Please contact Anuja A. Majmudar,
at (202) 551-3844 or, in her absence, Laura Nicholson, Special Counsel, at
(202) 551-3584 with
any other questions.
