There should be a minimum compensatory level mandated by law. This offer of Delta's can be rescinded later when the hoopla dies down.

My suggestion:

1. Cash $600 min to $5000.
2. Hotel - covered
3. Taxi - transport to hotel and back covered
4. Meal allowance: $20 per sitting

OR
1. Voucher $1200 to $10000 with a two year sunset clause.
2. Hotel - covered
3. Taxi - transport to hotel and back covered
4. Meal allowance: $20 per sitting
