Generally, an error message is the result of a temporary connectivity issue between GoEuro and the travel provider operating your route. Connectivity issues are rare but when they do occur your booking can fail at the last moment. Most of the time, these issues resolve themselves quickly and it’s simply a matter of trying your booking again an hour later.
Occasionally, an error message can be a consequence of something a little more technical. If you’ve tried to book a number of times without success, this may need investigating from our side, in which case the error message will let you know to contact our customer service team.
