Help from those who have flown out of LaGuardia on Delta. We will be on flight 667 leaving at 6:10 am. We should arrive 2 hours before flight time. Can anyone tell me if there will be Delta personnel there at 4:00 am? are any food counters open since we will be not getting the Delta deli breakfast in a bag? Deciding whether I should just pack food for my family and hope that we can still get beverages in flight. Thanks in advance!
