                                                        ended December 31, 2021
continue to be adversely impacted by COVID-19 and that the

2.       We note your revised disclosure in response to prior comment 3 that
APSG, with the
         assistance of its outside financial advisors, analyzed FY 2023E
Adjusted EBITDA
         multiples of several key comparable publicly-traded travel companies,
and that based on
         this analysis, APSG, in consultation with its outside financial
advisors, selected an
         Adjusted EBITDA multiples range of 11.0x to 12.0x FY 2023E Adjusted
         EBITDA. Please expand your disclosure to provide more details
regarding this analysis,
         including the publicly-traded travel companies selected and the FY
2023E Adjusted
         EBITDA multiples of these companies that were used in this analysis.
In addition,
         disclose the criteria used to select these companies. Please consider
including this
         information in a table or chart.

         Please also revise your disclosure to further explain how the
"investor friendly" discount
         of 15% applied to the valuation implied by this analysis was
determined and deemed to be
         appropriate.

3.       We note your response to prior comment 9 that Houlihan Lokey selected
and applied the
         same range of 9.0x to 11.0x to GBT   s FY 2019 Adjusted EBITDA and FY
2023E
         Adjusted EBITDA even though the selected companies analysis yielded a
2019 EV to
         Adjusted EBITDA low/high range of 6.3x to 34.9x and a 2023 EV to
Adjusted EBITDA
         low/high range of 5.1x to 13.6x due to (i) projected growth for GBT
for the period from
         2020 through 2023 being slower relative to that of the selected
companies (which
         supported a lower EV to FY 2019 Adjusted EBITDA multiple selection for
GBT) and
         (ii) some outlying multiples on the high end of the range of observed
EV to 2019 Adjusted
         EBITDA multiples. Please revise your disclosure accordingly.

estimates or
         assumptions underlying these metrics that should be disclosed.
