Every month the Department of Transportation issues the Air Travel Consumer Report. This month the report has statistics about tarmac delays — and the numbers aren’t good for Delta, United and their regional partners.

According to the data from the DOT here are the top 5 airlines with the highest percentages of regularly scheduled flights with tarmac delays of 2 hours or more:

1. Comair — this is a small regional carrier that flies under Delta’s name as “Delta Connection” and is a is a wholly owned subsidiary of the airline.

2. Delta

3. Atlantic Southeast Airlines — this company operates regional flights as both Delta Connection and United Express

4. United Airlines

5. US Airways

Both United and Delta could face hefty fines for their slothful ways — they were the only two airlines to operate flights that violated the new rules governing tarmac delays.

There were only two airlines that had no delays of 2 hours or more: Alaska Airlines and Hawaiian Airlines.
