Choose between train and flight by comparing the whole transfer. Include the journey to the terminal, required arrival time, baggage, security, delays, and the final trip into the city.
Compare like with like
Use the same travel date and passenger assumptions. Record door-to-door time, total price, flexibility, and where each option leaves you.
Consider the shape of the day
A central station may preserve more usable time than an outlying airport. A flight may still be sensible when the rail journey is long or requires several changes.
Verify the exact service
Check current schedules, engineering works, baggage rules, and change terms before paying. A planning estimate is not a live ticket quote.
