Please reconfirm my flight.
Literal
Flight-of reconfirmation [object-を] please.
An example of a mixed Japanese–English sentence: リコンファーム is the English 'reconfirm' directly loaned as a katakana word, used in travel and business contexts alongside the native 再確認. Such loanwords often signal industry-specific register — here, airline jargon. お願いします provides the polite request frame.
