We’re flying ATL-ORD-DOH-NBO New Year’s Eve. We have about 4 hours to spend in the Flagship Lounge and we don’t plan to check bags. So we’ll head to T5 about 45 minutes before boarding. We all have Clear and Precheck so I’m not too worried. Will skip whatever lounge delights T5 currently has. Will report back after.
45 minutes before boarding? Wow! I would go nuts with worry.
You might want to rethink 45 minutes...
You have to get to the train - 5-10 minutes.
Wait for the train - 5 minutes.
Take the train - 10 minutes.
Get off train and walk to security - 5 minutes.
Clear security - 5 minutes if you are lucky.
You are now 15 minutes before departure and still need to walk to the gate. And if any of those things take more than the allotted time, you misconnect.
I am slightly worried about 2 hours from touchdown to takeoff.
I am ahead of you; x-mas week. I will report back.
