We've gotten numbers in the the 40's both times and these's been no problem getting seats together. (there are three of us) If it's really important to sit together, get to the airport early and stand at the gate counter whether it's open or not. If you get a number 1-30, you're fine. If you get a number in the next group, I would then move over to the gate and be first in line for the 30-60 boarding. If you're in the 60-90 same thing. And if you're in the over 90 be pleasantly surprised if you get to sit together.
