The One Item the Queen Never Travels Without

• A new documentary revealed what's on the Queen's Royal rider, so you know what to bring her next time you invite her on holiday.

Considering we're all quite obsessed with The Royal Family, it's hardly surprising their travel habits have caught our attention. Whether it's why Kate Middleton books two seats when she flies on budget airlines, or how Meghan Markle and Prince Harry snuck onto a commercial plane without anyone even realizing, there's a real appetite for knowing about their holidays.

When it comes to the Queen, there's one item she won't travel without. In a new Channel 5 documentary, Secrets Of The Royal Flight, Royal Correspondent Emily Andrews touched on what it's like on the Queen's royal plane, and what the Queen puts on her rider (side note: no, she didn't call it a rider).

"She loves afternoon tea, it’s her favourite meal and she only drinks earl grey," Emily said. "So if you were the chef on board the Royal Plane you would definitely make sure that you had an entire supply of earl grey. Not just for the plane journey but wherever you were going on tour."

Speaking of what the Queen's favourite afternoon tea order is, Emily added: "She particularly likes egg and cress sandwiches cut in particular ways and for supper, she always liked to start with smoked salmon."

Interestingly, Former Royal Spokesperson Dickie Arbiter also said during the documentary that Elizabeth likes to travel with one specific type of water. "The only thing the Queen requests to have wherever she is is Malvern Water, he commented. "She likes Malvern water, it’s refreshing and they usually take lots of it with her."

Take note: if you invite the Queen over for tea, she'd like Malvern Water, Earl Grey Tea, and some egg and cress sandwiches.
