We definitely concur with @onyx007 . When I consider the process of getting to the airport early, then security, then the risk of not getting our carryon bag on the plane because of space or size, the plane is just more stress. Then there's the risk of it not leaving on time. I don't want to fly on the small KLM City aircraft. From the port to the train station via the Tram is only 15-20 minutes. And then we're on, shortly after. I feel more relaxed on the train. Yes, we have to go through immigration off platform, and then connect to next train. But that's not that bad. We have musical tickets for two shows in London. But neither is on the day our train arrives.
