Ahead of Queen Elizabeth II's funeral, scheduled to go ahead on Monday 19 September at Westminster Abbey, one thing has already reportedly been banned.
The Queen passed away in her Balmoral Estate on Thursday 8 September at age 96, after a 70-year reign.
As diplomats, world leaders, and other VIPs make plans to attend the ceremony, they'll have to overcome one specific request.
According to documents seen by Politico, notable visitors will be encouraged to take commercial flights to the UK and take escorted coaches from a site in west London, rather than travel by private jets and state cars.
So, if you see Joe Biden and Emmanuel Macron fighting over who gets to sit at the back of the bus next week, now you know why.
The note from the FDCO (Foreign, Commonwealth & Development Office) advises that, 'where possible', heads of state and their partners should arrive on commercial flights. It also warned that London's Heathrow airport will not be available for any private flight arrangements, so those who insist on travelling by private jet should opt for 'less busy airports'.
LADbible has approached Buckingham Palace for a comment.
Meanwhile, for those who were hoping to take the chopper to London, helicopter transfers from airports to venues have been banned 'due to the number of flights operating at this time'.
In the build-up to the state funeral, members of the public have been lining up to pay their respects at the Queen's coffin in Westminster Hall, while the new King Charles III returns home after a busy week of duties and prepares to host a reception for overseas leaders.
The documents cite that the new monarch will host special guests and their partners at Buckingham Palace on Sunday 18 September, the evening before the funeral.
Attendees will also get their own opportunity to attend the Queen's lying-in-state and sign the book of condolences at Lancaster House.
The following morning, heads of state and their partners will be asked to leave their state cars at a designated spot in west London and get on a coach to Westminster Abbey.
When the funeral finishes, Queen Elizabeth's coffin will be brought from Westminster Abbey to Wellington Arch, and then to Windsor, before it's driven in the state Hearse to St George's Chapel.
For those who haven't been cordially invited to the grand-scale ceremony, Monday 19 September will be a national bank holiday in England, Scotland, Wales, and Northern Ireland.
The bank holiday will allow businesses, organisations, and individuals to pay their respects and commemorate Queen Elizabeth, and mark the final day of the period of national mourning.
