Cheap flights from Harrisburg (MDT) to Nassau (NAS) from $416

This was the absolute WORST experience--and as someone who experienced what Southwest went through this past December, that is saying A LOT. Delta blamed "weather" which we all know was so they didn't have to be accountable. I was watching the weather radar in the Atlanta, which is where the "storm" was. It cleared by 6pm--and the fact that I left West Palm around 8:30--got in around 10:30, our next flight was scheduled for 12:30a. What did Delta do? They boarded us in time for the flight--and we sat on the plane ready to go--full to the max for an HOUR AND HALF. We were told shortly after we boarded that the pilot had landed and was on his way to our plane. An hour and half later, no pilot, we were told he had "timed out" and we were asked to deboard. This is at 1:30AM. I am traveling with a 7yo. When approaching the desk, the representative, Al, said we would receive our next flights via "text". Mine separated my 7 yo and I!!! After some work, this was resolved and when I asked about vouchers for a hotel--I was told there were no opening in the local hotels. How did he know? Didn't even offer to help. He then printed me out 2 $15 food vouchers (at 2am--and nothing opens until 6am). I sat on the floor, concerned more than comfort for even safety--for the next 6 hours with my 7 year old (which would have been great time spent in a hotel). At 6 am we went to Dunkin, and they refused the voucher, stating we needed to give our receipt to the agent at the counter. When I did that before boarding, I was told that was also NOT correct and I had to do something with a website--before--which I was not told--and needless to say, I was unable to use. I was treated poorly by all agents. I understand they're tired and frustrated--but they're also on the clock being paid. I am a customer. When I asked for a number to call for support, Al told me to "google it!" Can you imagine?! Southwest went through something horrific--but they HANDLED it well. No one is saying "weather is your fault", but being honest and how you're handling a clear shortage of pilots is critical in us making our future plans to travel with Delta. Not to mention, I PAID for Comfort Plus seating and was sat in the very last row, seat 32. I was told no one could anything about it, so I would have to contact and waste even more of time dealing with a 1-800 number for MY OWN refund!! After the AWFUL trip here--I am EXHAUSTED dealing with your representatives and have lost countless hours battling for simple, just and fair treatment and response to PAID services.
