Delta is a greedy airline that overbooked my flight I had planned waaaaaaaay in advanced. Had no seats for me and my brother and had us wait until someone willingly gave up there seat. Forced my to check my BRAND NEW carryon luggage MEANT TO BE CARRIED ON. First and last time flying delta. I’d rather fly spirit at least they didn’t pull this.
