Booking Experience

I started my search on Google Flights, which remains my go-to platform for comparing prices across multiple airlines. I noticed the lowest prices were roughly 21 to 30 days in advance, especially for weekday departures (Tuesday or Wednesday). I eventually booked directly through the American Airlines website, which offered more flexible seat selection and an easy interface for applying my AAdvantage miles (though I opted to pay in cash this time).

I chose a basic economy seat for the outbound leg and added a main cabin upgrade for my return trip, just to test the difference.

The Flight Itself: A Personal Review

Check-In & Boarding

I used the mobile app to check in the night before and didn’t need to print anything. Security at PHL Terminal F was surprisingly smooth—only 15 minutes. Boarding was done in groups, and since I was in Basic Economy, I boarded in Group 8. It felt like the entire plane was already full by then, and overhead bin space was limited.

TIP: If you value overhead space or want to avoid gate-checking your carry-on, pay extra for Main Cabin or book early to get higher boarding priority.

Onboard Experience

The CRJ-700 is a regional jet, so seating is 2-2, and the overhead bins are a bit tight. As expected, legroom was snug, but manageable for such a short flight. The seats were clean but worn—thin cushioning, no seat-back entertainment (bring your own tablet!).

Flight attendants offered water, coffee, and cookies—a pleasant surprise for such a short flight. The landing was smooth, and we even arrived 10 minutes early.

Emotionally? It felt surreal to go from one major U.S. city to another in barely over an hour. I had time for breakfast in Philly and lunch at the Wharf in D.C.

📅 When to Book for the Best Deals

After tracking this route for several months via Google Flights, Hopper, and Kayak, here’s what I learned:

  • Book 21–30 days in advance for the best balance of fare and seat availability
  • Fly midweek (Tuesday or Wednesday) to save 10–15% on average
  • Morning flights (before 11 AM) are more reliable and less prone to delay
  • Use flight tracking tools (Google Flights “Track Prices” or Hopper alerts)
  • Avoid major holiday weekends unless booked at least 2 months in advance

🛫 Nearby Airports to Consider

If you’re flexible, these alternative airports can offer better prices or more schedule options:

Philadelphia Area

  1. Philadelphia International Airport (PHL) – Major hub; American Airlines stronghold
  2. Trenton–Mercer Airport (TTN) – Allegiant and Frontier low-cost carriers; far fewer flights
  3. Atlantic City International (ACY) – Cheapest flights but limited options

Washington Area

  1. Ronald Reagan Washington National (DCA) – Closest to downtown; best for business trips
  2. Washington Dulles (IAD) – Larger airport, but ~45 minutes from D.C.
  3. Baltimore-Washington International (BWI) – Good prices; accessible by MARC train

🧳 Final Tips and Takeaways

Here are a few nuggets of wisdom I picked up from this quick but surprisingly complex route:

  • Pack light. Avoid checking bags unless absolutely necessary. For short flights like this, even a small carry-on can slow you down.
  • Check Amtrak. If airfare spikes above $200 round-trip, Amtrak Acela or Northeast Regional could be better value and less stress.
  • Use airline miles for short-haul redemptions; this is where they stretch furthest.
  • Arrive early at PHL. Terminal F (used for regional flights) is small and efficient, but still plan for TSA delays during peak morning hours.
  • Consider pairing your trip with events in either city. I booked mine around the Smithsonian’s Folklife Festival and got more value from the trip.

My short flight from Philadelphia to Washington, D.C. reminded me of something simple yet profound: even the briefest journeys deserve our attention, our planning, and, most of all, our appreciation.

At first, I thought this would be a straightforward, uneventful domestic hop. But as I compared airfare options, navigated airport logistics, considered which airport in D.C. to fly into, and experienced the flight itself, I realized just how rich this “simple route” really is. It’s a microcosm of everything we deal with as travelers: choices, trade-offs, surprises, and sometimes—serenity.

If you’re traveling as a family, especially with small children, I strongly recommend booking morning flights. Kids tend to be more rested, airports are quieter, and the risk of delays is much lower. Also, avoid Basic Economy tickets if you need seat assignments to stay together—it’s worth the extra cost for peace of mind. Flying into DCA (Reagan National Airport) is by far the best option for families, as it’s the closest to downtown and minimizes ground transport stress.

For business travelers, this route is a gem. Reagan National is just minutes from Capitol Hill and K Street, making it perfect for quick in-and-out trips. Booking early-morning weekday flights ensures punctuality, and enrolling in frequent flyer programs helps turn even short flights into elite status points. If your company has a preferred airline portal, use it to take advantage of business class upgrades or flexible change policies. And avoid booking last-minute unless absolutely necessary—fares tend to spike dramatically within five days of departure.

If you’re a budget traveler or student, this route still has great value. Flexible dates are your biggest weapon. Use Google Flights or Hopper to set alerts and monitor pricing trends. I’ve found that Tuesday and Wednesday departures are consistently 10–15% cheaper than Friday or Sunday. If airfare jumps above $200 round trip, seriously consider Amtrak—especially the Northeast Regional service, which often matches or beats plane ticket prices without the baggage fees or TSA hassles.

Now, for those of you who are first-time flyers, don’t be fooled by the short flight duration. Even a one-hour flight can take up to three hours from curbside to arrival gate. Always arrive at least 90 minutes early, download your airline’s app for real-time updates, and pack a snack and a water bottle (after security, of course)—regional jets don’t always provide full service. And be mindful of carry-on limitations in Basic Economy. I saw multiple travelers forced to gate-check bags because they didn’t read the fine print.

I flew out Friday morning, had two full days to explore D.C., and returned early Monday—refreshed and recharged. D.C. is an incredibly walkable and accessible city, with world-class museums, free exhibitions, iconic landmarks, and seasonal festivals like the Cherry Blossom Parade and July 4th fireworks on the National Mall. The best part? Many of these experiences cost nothing at all. A smartly timed short flight can open the door to a weekend of discovery.

And what did I learn most of all? That value in travel doesn’t always come from distance or extravagance. Sometimes it’s about timing. About having the right seat at the right hour. About the ability to adapt—whether that means choosing the better airport, skipping the baggage line, or opting for a train when airfares surge. Travel is never just about getting somewhere; it’s about how well you do it. This short hop between two East Coast hubs reminded me of that truth.

So if you’re planning your own trip from Philadelphia to Washington, don’t underestimate this route. Give it thought. Give it planning. Look at the booking window. Compare airport options. Decide what matters to you—price, schedule, comfort—and build your trip around that.

Because even a one-hour flight can teach you something—about travel, about yourself, and about how every journey, big or small, deserves to be done well.

Wishing you smooth skies, short lines, and meaningful arrivals.
