Prince Harry doesn’t want to waste time whenever girlfriend Meghan Markle is in London.

According to Express, the royal prince usually collects the "Suits" star straight from the tarmac to avoid the queue at the airport when she arrived in the capital of England. A number of sources at Heathrow claimed that this has happened a number of times already. The most recent one was in May, when the "Horrible Bosses" star arrived from Toronto for Pippa Middleton's wedding.

"It's been happening for a while," a source told the publication. "Harry has a police escort on the tarmac in his black Audi RS6. He is accompanied by a bodyguard, with a people carrier following behind."

The source added that Markle usually only carries hand luggage. If she checks in a suitcase, they will usually put it in last, so it can be located immediately. In addition, all the necessary security checks are done in advance or onboard the flight because upon arrival, she walks straight from the plane to Prince Harry's car.

Another insider revealed that the couple was offered the use of the Windsor Suite, where VIPs are escorted directly to their aircraft away from the masses after the security checks. However, Prince Harry declined it because the service is expensive. It costs around £3,000 ($3,847). Thus, he made his own arrangements.

Meanwhile, with Markle and Harry's relationship getting more serious, many are wondering about when their engagement will happen. In fact, when the pair headed to Africa for Markle's 36th birthday, the engagement rumors intensified as this was where Prince William proposed to wife Kate Middleton.

Although there was no engagement announcement at the time, the British tabloids have been claiming that the royal has already popped the big question. The British betting world also believe that the proposal is already a done deal. Currently, they no longer bet on when Prince Harry will propose, but on when the next royal wedding will happen.

To confirm Harry and Markle's engagement, fans should wait for the palace's announcement. It will usually be done early morning on its social media account. After the official announcement, the couple will have a joint interview.

Usually, the proposal happens a few weeks before the official announcement. When Prince William and Middleton disclosed their engagement, the Duke of Cambridge admitted that he proposed to the Duchess when they were in Kenya a month before the public announcement.
