Prince William may be a royal, but that doesn't mean he always has to be given the royal treatment.
Case in point?
The Duke of Cambridge's decision to fly coach on an American Airlines flight from Memphis to Dallas on Sunday as part of his trip back to London after attending the weekend wedding of his pal Guy Pelly.
"I am still amazed #PrinceWilliam flies COACH," tweeted TV reporter Eli Ross, who was on the same flight as William, along with a photo of the future king sitting in a window seat. "That's prety humble/awesome. Who knew?"
Prior to the flight, Ross posted another pic of William, writing, #PrinceWilliam leaving @AmericanAir Admirals Club at #DFW. Headed to gate."
While Prince Harry was not seen on the plane, a source told E! News that he left town on Sunday as well.
The day before, the brothers watched Pelly tie the knot with Elizabeth Alleen Wilson, granddaughter of the Holiday Inn Hotel founder.
William and Harry arrived at the Memphis Hunt and Polo Club at 5:30 p.m. on Saturday to attend the formal ceremony, with guests taking their seats on white chairs in a garden, a source told E! News exclusively.
"The bride arrived in a classic blue Thunderbird just before the 6 p.m. ceremony began," the source continued. "A boys' choir performed along with a cello ensemble. Lizzie looked beautiful in a jeweled dress with a sheer overlay and a crown of white flowers in her hair."
The couple's vows lasted about 30 minutes, with William and Harry looking "overjoyed" for their friend during the ceremony. "You could see they are very close," the source added. "They were all hugging each other and shaking hands."
