Hi

A group of us are flying BA from ATL to LHR in the next few days. A mix of First and Business. The reviews are pretty bad with this being the main hub for Delta. Can I clarify a few things

1. Is there a dedicated check in area for first or business class
2. Is there expedited security lane
3. Is the lounge as bad as reviewed ? Will first class passengers be able to dine before boarding ?


Thanks
