David Owen in The New Yorker:
When you sign up online for Skywards, which is the frequent-flier program of Emirates, the international airline of the United Arab Emirates, you enter your name, address, passport number, and other information, and you select an honorific for yourself from a drop-down list. A few of the choices, in addition to the standard Mr, Mrs, Ms, Miss, and Dr, are: Admiral, Air Comm, Air Marshal, Al-Haj (denoting a Muslim who has made a pilgrimage to Mecca), Archbishop, Archdeacon, Baron, Baroness, Colonel, Commander, Corporal, Count, Countess, Dame, Deacon, Deaconess, Deshamanya (a title conferred on eminent Sri Lankans), Dowager (for a British widow whose social status derives from that of her late husband, properly used in combination with a second honorific, such as Duchess), Duchess, Duke, Earl, Father, Frau, General, Governor, HRH, Hon, Hon Lady, Hon Professor, JP (justice of the peace?), Judge, Khun (the Thai all-purpose honorific, used for both men and women), L Cpl, Lt, Lt Cmdr, Lt Col, Lt Gen, Midshipman, Mlle, Monsieur, Monsignor, Mother, Pastor, Petty Officer, Professor, Senor, Senora, Senorita, Sgt, Sgt Mjr, Shaikha (for a female shaikh, or sheikh), Sheikh, Shriman (an Indian honorific, for one blessed by Lakshmi, the Hindu goddess of wealth, wisdom, luck, and other good things), Sister, Sqdn Ldr, Sqn Ldr, Sub Lt, Sultan, Swami, The Countess, The Dowager, The Duchess, The Marquis, The Matron, The Rev Canon, the Reverend, The Rt Hon, The Ven, The Very Revd, Ven, Ven Dr, Very Revd, Vice Admiral, Viscount, and Viscountess.
Anyone who chooses King obviously goes in first class, Private in economy, Wing Cmdr in an exit row. But what about Cardinal?
