Prince Harry's memoir, Spare, has made headlines around the world for its sensational claims about the Royal Family. Some of the instances that he has mentioned in the memoir is under scrutiny like the details of one incident about his father-in-law. 


Harry has said that his wife Meghan Markle had booked a first-class seat on an Air New Zealand flight from Mexico to England in 2018 for her father, Thomas Markle, who was under heavy press scrutiny for allegedly staging paparazzi pictures. 


However, the airline responded that it has never operated a flight between the two countries and offers a Business Premier service rather than first class, reported news agency AFP.


Denying the claims the airlines also took a dig at Prince Harry on social media Friday, promoting a "SussexClass" in response to the Duke of Sussex's claim.


"Introducing #SussexClass, apparently coming soon," Air New Zealand posted on the social networking sites Facebook and Twitter,  in reference to Harry and Meghan's titles of Duke and Duchess of Sussex.






One user after seeing the post commented, "Look forward to travelling Sussex Class - hope my bags make it."






"I knew there was a reason why out of all the airlines I’ve been on, AirNZ has been top tier," wrote another jokingly.






Meanwhile, the English version of Prince Harry's memoir has sold a "record" 1.4 million copies in its first day of publication.


"The first full day of sales of Spare represents the largest first-day sales total for any nonfiction book ever published by Penguin Random House, the world's largest trade publisher," Penguin Random House said in a statement, according to CNN.


The 410-page memoir that officially went on sale on Tuesday has "gone back to press for additional copies to meet demand" as the first US printing of Harry's memoir was 2 million copies, reported the media house.


Harry and Meghan resigned from royal duties in 2020 and moved to the United States where they signed several lucrative contracts for tell-all books and television programmes, reported AFP.
