(Sorry for this necrobump, but it really is the most appropriate thread title.)

Now with all of the chaos at ARN, does anyone still think this is possible? If so, how late are the ticket counters open now?

We initially were going to take an overnight bus to ARN, arriving around 4am, and I'm pretty sure we won't be allowed into T5 until 7:20am to check-in for our ARN-ORD flight. I've now pondered maybe taking a late afternoon bus the day before in order to do early check-in of our bags to avoid one additional potential headache, stay at a hotel, then simply try to clear security at T-3 hours.
