Omio is an online ticket agency which offers tickets for rail journeys in France, Germany, Great Britain, Italy and Spain.

The three key advantages of using Omio are

• it offers prices in multiple currencies
• it usually offers price comparison with other modes of travel including flights and buses
• when visiting Europe, you can book journeys in multiple countries in one transaction.

The disadvantage of booking with Omio is that it often adds a booking fee to the final price; therefore when it does so without offering a price advantage, SMTJ doesn't tend to offer Omio as a booking option.
