Kate Middleton traveling by herself for the first time as a royal

We already know Kate Middleton is one of the best-dressed travelers around, stepping down jet stairs chic, yet practical outfits paired with versatile (and comfy!) travel shoes. This week, on her first solo trip as a royal, the duchess stunned in another way: surprising passengers aboard a commercial flight headed for London.

After her one-day trip to Holland, the princess boarded a British Airways flight in Rotterdam for her return trip to London. Passengers snapped photos as she took her seat in the front of the plane wearing a light blue Catherine Walker suit that had almost a vintage flight attendant feel—perhaps she was channeling her mother, Carole Middleton, who formerly worked for the airline. Once the short flight was over she was escorted off the plane where a private car was waiting on the tarmac.

The one-day trip to the Netherlands included a visit to the Mauritshuis museum in Hague, where she visited students in the gallery’s learning program (reminder: Middleton was art history major in college). The duchess also greeted fans and attended a reception at the museum, as well as met with the Dutch monarch King Willem-Alexander at the British Ambassador’s Residence.
