Crew and customer service are 5 stars. I had a lot of luggage for a very long trip and they were nothing but helpful and found solutions to every problem. It was my first time flying with United, and they really are the friendly skies. Leg room however, on 2/3 flights was terrible. Same for entertainment: There was only a seat-mounted screen on 1/3 flights. It would have been nice to have on the longest leg of the journey.

Washington climate

The busiest seasons for tourist activities are spring and summer, in particular during the time when the cherry blossoms bloom and when schools are out for spring break and then summer holiday.

The grounds are as lovely as the building, with gardens and a lawn where you can picnic. In addition to religious services, the cathedral offers guided and audio tours, recitals and concerts. Music lovers can visit the Cathedral for the twice-weekly lunchtime recitals on the magnificent Aeolian-Skinner organ, or attend one of their concerts (classical, jazz, folk) throughout the year.
  • There is always something to attend at the John F. Kennedy Centre for the Performing Arts.
