Should I give up on traveling from Copenhagen to Stockholm by high speed train and just fly?

I checked the Swedish website and it also says that they are not selling tickets between July 3 and August 13 because they don't have sufficient capacity to carry out ID checks. It says that they are working with Danish transit authority on a solution.

I am speculating, but this date range could be due to the fact that most Swedes take their vacation in this period. Swedes are entitled to take 4 consecutive weeks of vacation during the summer and most people take vacation in July.

I think I would look for a flight as prices will go up if you wait.

The situation for the past few months has been, that Sweden has introduced ID checks at it's bordersfor an undetermined period. This means that there are no direct trains between Denmark and Sweden, you have to change trains at Copenhagen Airport Station (the last stop before Sweden) and have your ID checked before entereing the Sweden bound train. Currently the high speed train to Stockholm runs from Malmø, so the train trip from Copenhagen Central would involve two changes, one at Copenhagen Airport for the ID check and one in Malmø.
I did a search on the Swedish Railways and it inducates that all trains affected by this (with less than 2 changes) are listed as sold out, though it probably means they are just not available.

The direct train between Copenhagen and Stockholm is quite competitive with planes, both on price and time. It's a little over 5 hours vs. about 4-4,5 on the plane including getting to and from airports, however the train wins on convinience (city centre to city centre).
However if you have to change trains 2 times that convinience is lost and the plane wins hands down.

Thanks to both of you for excellent advice! I will go ahead and buy the plane tickets while the price is good.

I'm looking to do the same thing on July 5 with my family (2 adults, 2 kids). It looks like the only option has two stops and takes about 6 hours including stops for 986 Swedish krona (?). This price seems super low but when I go to the site and pick English, it doesn't indicate what the currency they are listing the prices in.

wow, had not heard this. How about the other way around, from Stockholm to Copenhagen? That is the plan I am working on for mid-August. And then fly back to the US from Copenhagen. Thanks.

Is an overnight trip worth it? We are considering Stockholm vs Aero.

@WJT - I think it's pretty fair to assume that the Swedish national railways lists their prices in Swedish Krona.

@Stewart - There is no border control when entering Denmark from Sweden and it looks like you can get direct train tickets from Stockholm to Copenhagen. have a look at www.sj.se.

@coffii_howz - I would allow at least as much time to Stockholm as I would to Copenhagen, both ciites are similar in terms of size and number of sights.

Hello, I am trying to figure our a similar route for either Copenhagen-Stockholm, or the other way around. I saw the same thing as was previously mentioned on the SJ website where all direct trains from Copenhagen are showing up as "sold out" and the only options are with 2 stops (obviously increasing travel time). However, at the same time, Scandinavian Rail http://www.scandinavianrail.com (have not used it before) is showing availability and very inexpensive direct options from Copenhagen to Stockholm. If I am reading it right, it's showing me a price of $59 for an option with 2 adults and 2 kids under 11. It seems rather strange though that if in reality there are no direct trains, why they are offering this option for purchase. Any experience with them?

It appears that the ID control for the SJ High speed trains has been moved to Copenhagen Central Station, thus eliminating the need for changing trains in Kastrup and Malmø. https://www.sj.se/en/home/id-controls-in-copenhagen.html
A quick search showed that direct tickets are available.
@524slava I have never heard of scandinaviarail before, but there is no need to buy tickets through a third party, they will only charge their cut for it. Buy directly from SJ

I'm going Copenhagen in 2 weeks and bought a Norwegian Air plane ticket from Copenhagen to Stockholm for 49 USD. Sounds to me like flying would be better all the way around.

We used the high speed train from Copenhagen to Stockholm June 18. Everything was great. I purchased my tickets far enough in advance that the price worked out to about $64 per person. 5 1/2 hours from center of town to center of town.

Just to mention for any lurkers out there, there still seems to be an issue with high speed trains between Stockholm and Copenhagen. I've also posted on the Sweden forum. sj.se is showing direct non-stop trains available, but only up to Aug 8, after that date the direct trains are listed as "sold-out". A reply I saw was that they are still working out the details of their border control check, and they "may" open up later dates as they get closer to those dates.
