Prince Harry and Meghan Markle were recently criticized for travelling by private jet.
The couple reportedly took three different private aircrafts in the space of a month, right after urging fans to be aware of climate change.
Most recently, Elton John said he paid for the couple to travel to his home in Nice.
Although it could be considered unsafe for them to fly commercial — as pointed out by Jameela Jamil, who said they are "prime targets" for kidnap or even assassination — that didn't stop fans from questioning their decision.
One person who stayed out of the drama is Queen Elizabeth II.
Her Majesty is known to travel by train, bus, and even the London Underground, when her schedule permits.
The monarch looks like a lot of fun to travel with, too — she sometimes even brings her pet corgis along for the journey.
Insider has rounded up the best photos of Queen Elizabeth taking public transport.
Queen Elizabeth may be the monarch of the United Kingdom, but that doesn't mean she won't take the bus like a regular citizen.
She travelled by bus to an engagement at the Medical Research Council in Cambridge back in 2013.
She's also partial to the underground.
Like every Londoner, Her Majesty knows the struggles of rush hour travel.
She used the Victoria Line after its official opening in 1969...
... and she travelled by tube again in 2013, to mark the 150th anniversary of the London Underground first opening.
Both the Queen and Prince Philip have been known to travel by train over the years.

The couple were accompanied by Scotland's First Minister, Nicola Sturgeon, on a service from London to Tweedbank in 2015.
She'll even bring her pet corgis along for the ride every now and again.
Meghan Markle also got to experience what it was like to travel with the Queen. In 2018, they took an overnight train to Cheshire before attending their first joint engagement together the next morning.
