Public Bus Options from BWI to Washington D.C.
For the most budget-conscious travelers, public buses offer the lowest cash prices but require transfers and significantly more time.

| Route | Schedule | Fare | Travel Time | Key Information |
|---|---|---|---|---|

- Light Rail: To Baltimore Penn Station ($1.90)
- MARC Train: Baltimore to Washington D.C. ($7)
Total cost: $10.90 | Total time: 2+ hours

Greyhound and Peter Pan operate from Baltimore Downtown to Washington D.C., but require additional transportation from BWI to Baltimore bus terminals (adds 60+ minutes and $10-20). Not recommended for airport transfers unless combining with other Baltimore activities.
Bus Travel Considerations:
- Buses have limited luggage capacity (2 checked bags typically)
- Allow extra time for Metro transfers during rush hour
- Greenbelt Station parking fills by 8 AM on weekdays

Rental Car from BWI: Is It Worth It for D.C. Visit?
Renting a car at BWI for a Washington D.C. visit requires careful consideration due to D.C.'s parking challenges and congestion.
Rental Car Practicality Analysis
| Scenario | Rental Recommended? | Key Factors |
|---|---|---|

| Business with multiple suburban meetings | Yes | Time efficiency may outweigh parking/traffic hassles |
