Exhibit 99.3

Golden Falcon Acquisition Corp.

December 07, 2022

Dear All,

We are pleased to let you know that today we announced that MNG Havayollari ve Tasimacilik A.S. (“MNG Airlines,” “MNGA” or “the Company”), a global logistics provider and e-commerce enabler, has entered into a definitive agreement to become publicly traded via a business combination with Golden Falcon Acquisition Corp. (“Golden Falcon”). The transaction is expected to have a pro-forma enterprise value of $676 million, assuming gross transaction proceeds of $30 million, implying a 5.8x multiple on LTM Adjusted EBITDA as of 30 September 2022.

Throughout 2021 and 2022, we have vetted over 500 companies as potential combination partners. We have conducted in-depth due diligence on a number of them and were well positioned to combine with some of those other companies. That being said, as we stressed to you at our IPO, we were focused on combining with a company that we believed would be an attractive investment in both the short-term and long-term. Specifically, we said we were focused on combining with a company that had a set of specific attributes. As you can see, we believe MNG Airlines as an investment opportunity reflects the attributes we sought to achieve:

• Established company with a track record: MNGA has 25 years of operating experience servicing over 15,000 corporate customers across 41 countries on 4 continents

• In the Europe, Middle East, and Israel region: MNGA is strategically located at the heart of the modern Silk Road, and in one of the largest and fastest-growing air cargo markets globally

• Secular market tailwinds: increasing demand for express air cargo coupled with historical air freight growth at a 3x multiple of global GDP growth (1973-2019, according to IATA data); supply-side constraints on meeting global need for dedicated freighter capacity

• Strong growth profile: for the last twelve-month period ending 30 September 2022, MNGA’s revenue grew by 39% year-on-year to $353 million. MNGA e-Commerce revenue grew to $82 million in the last twelve months ended 30 September 2022, from zero in 2020

• Cash flow generation: MNGA has been net-income positive for the last 10 years, and for the last twelve-month period ending 30 September 2022, MNGA delivered net income of $61 million, and adjusted EBITDA of $116 million (33% margin)

• Clear transatlantic nexus: MNGA has recently started flying to both New York and Toronto, and has identified multiple growth levers in North America, namely through potential long-term capacity agreements with leading logistics players and/or potential complementary acquisitions

• Committed shareholders: MAPA Group has been a supportive shareholder of MNGA since inception, and is expected to continue to retain a significant stake in the Company

MNG Airlines is a global logistics provider and e-commerce enabler, servicing over 15,000 customers across 41 countries through over 3,500 flights per year. The Company’s business model has four complementary segments: Scheduled & Block Space, Charter, aircraft, maintenance, crew and insurance (ACMI), and Warehouse & Handling. The Company’s cost base is mostly variable, with cost of goods sold representing 95% of its overall cost base in 2021. Company contracts have limited exposure to fuel costs, which are either 100% pass-through to the end customer (for charter flights and ACMI) or updated every two weeks (for scheduled flights). Revenues are generated in USD, EUR and GBP, collectively accounting for 98% of the total. The Company has been net income-positive for the last 10 years.

We believe the Company is well positioned for future growth as it sits on top of attractive secular trends. E-commerce tailwinds, an increasing focus on supply chain security, and a need for larger and more efficient dedicated freighter capacity are driving air freight demand. Global air freight has historically grown at more than 3x global GDP growth (1973-2019). More specifically, express air cargo market is forecasted to grow at 5% per year, 1.8x the rate of general cargo (2019-2041, according to Airbus data). Additionally, MNGA is strategically based in one of the largest and fastest-growing air cargo markets globally; air transport freight has increased in the region at ~10x the global rate, growing at a CAGR of 23% from 2009 to 2019 (vs. 2% worldwide), according to World Bank data.

We’ve been engaged with the Company for ten months and are pleased that financial success has continued, most recently in the third quarter of 2022. For the three months ended 30 September 2022, the Company’s revenue grew by 47% year-on-year to $90 million, net income of $26 million and adjusted EBITDA of $27 million (30% margin). Last twelve months revenue grew by 39% year-on-year to $353 million, net income of $61 million and adjusted EBITDA of $116 million (33% margin). Revenue has grown at a 37% compound annual growth rate between 2019 and the twelve-month period ended 30 September 2022 during this period.

As you may know, we filed a definitive proxy statement with the Securities and Exchange Commission on November 21, 2022, to seek our stockholders’ approval to extend our business combination deadline, and the special meeting of stockholders will be held on December 16, 2022. We urge you to read the definitive proxy statement carefully and vote in favor of the extension. Additionally, we believe that MNGA is a compelling investment opportunity. Notwithstanding the Company’s 30%+ revenue growth rate and 30%+ EBITDA margin on a scale business with $100m+ EBITDA in the last twelve-month period ending 30 September 2022, we’ve secured a valuation that we believe is the lowest multiple of EBITDA of closed DeSPAC business combinations to date in 2022, and offers a compelling value proposition even in the context of the close to 7,000 publicly listed companies in the U.S. We therefore hope that, subject to your diligence, you will not redeem your shares in connection with the stockholder vote and that you will be a continuing stockholder of GFX and MNGA should the business combination close as expected in the first half of 2023. In light of the fact that we expect there will be another opportunity to redeem by June 2023, we urge you not to redeem until you have reviewed the merits of the proposed transaction. We’re excited about bringing the proposed business combination with MNGA to you and we hope that you will share our enthusiasm.
