Gray Eagle02, as I read the email, CWN is correct. The email only applies to air reservations made by Regent on or after November 1, 2022. Since you made your air reservations yourself, the email does not apply to you. As the GIF states: “If your title is incorrect below, or your name does not match your name as it appears on your passport, please call Reservations to correct it.” So just call reservations to correct your middle name on the GIF and you should be good to go.
