Our son had a recent experience with Delta in First Class and will never fly Delta again. The flight out of DEN to MSP was delayed on the tarmac. The kids were bored to death, the flight arrived barely in time for them to catch their connection from MSP to Myrtle Beach. The gate was two gates away. They had five minutes to get there, the doors were closed, and the plane was backing away from the gate (five minutes early). At least 20 other people were left at the gate.
The gate agent booked them in economy to Raleigh, the flight again was delayed and they missed the connection to Myrtle Beach from Raleigh. Everyone gone from Raleigh terminal. No one could help them get a hotel or anything, so they had to scramble (plus their luggage was nowhere to be found).
No hotels because of the PGA tournament in Raleigh. A rental car company rented them a car for one day for like $400, and they drove to Myrtle Beach and arrived at 2 AM after one exhausting travel day. The rental car company had no car seats for the twins who are 2.5 years old. Their own car seats were God knows where. The 7-year-old is supposed to sit in a booster seat by law. The twins had a good time unbuckling and buckling their seat belts. It was a disaster of a trip.
Our son is usually not a flexible person, pretty grouchy guy, but he was just glad the ordeal was over and was grateful to get to the Sheraton.
