Flight delayed from 7:45 to 1:00 Pm. No effort from delta to reschedule. Left me arriving after my connection departure. I had to rebook. Myself. But no seat assignments. Put me in last seat that doesn’t recline. This was returning from Florida. Going to Florida my flight was cancelled. I had to rebook on another airline that cost me double.
