Archer Aviation, the electric aircraft startup targeting the urban air mobility market, has landed United Airlines as a customer and an investor in its bid to become a publicly traded company via a merger with a special purpose acquisition company. 

Archer Aviation said Wednesday it reached an agreement to merge with special purpose acquisition company Atlas Crest Investment Corp., an increasingly common financial path that allows the startup to eschew the once traditional IPO process. The combined company, which will be listed on the New York Stock Exchange with ticker symbol “ACHR,” will have an equity valuation of $3.8 billion.
