Seasons 1 and 2 of Arrow are already available for streaming on Netflix, and soon we will get season 3 as well as The Flash season 1. On the same day their next seasons air to be exact. So if you want to DVR or Hulu the episodes you can stream the previous seasons and then catch up on the current one I suppose.
Here I’ve compiled the streaming order if you want to marathon watch without watching the crossover episodes out of order. That way you don’t have to go back and forth every episode. (Which would be super annoying IMO.)
Start with Arrow, Season 3 Episodes 1-7.
Then marathon Flash, Season 1 Episodes 1-7.
This brings us to our first cross over.
Flash Episode 8, Arrow Episode 8. “Flash vs. Arrow” and then “Brave and the Bold”
Then you can do either show. We have a minor cross over in Flash Episode 18 where Ray Palmer and Felicity Smoak go to Central City, and in Flash Episode 19 we see Cisco and Joe in Starling City with Detective Lance. Therefore you should watch up to 17 in each, and then watch Flash 18, Arrow 18, Flash 19, and Arrow 19. However if you don’t, I don’t think it was major enough to spoil anything for you, regardless of which you watch first. Other than you should definitely watch Flash 19 before Arrow 19, because of something Cisco does while in Starling.
Then back to watching either up until you get to almost the finale (which are both 2-parters). Flash 22, Arrow 22, Flash 23, Arrow 23. Is the official way, but I’d rather watch both Arrow episodes and then both Flash episodes and reconcile them in my head later.
