This was the worst flight ever. Stuck on the TARMAC for over 2 hrs. Then returned to airport and reboard. Missed our connecting flight but the flight crew that was with the delayed flight didn't miss the boarding and continued on. They didn't even tell us where to go and we could have made our original flight. The later flight they booked us on was delayed an extra 2 hrs. So our flight from San Diego to DC started a 6a and we landed around midnight. Roughly 18 hrs stuck in the most uncomfortable seats, look and feel like military plane KC-10 seats (bare basic metal frame with foam to cover it). No entertainment or charging plugs. Food and soda was priced ridiculous ($3.99 for a can of coke). The only thing free was water. I would never recommend flying this airline unless it was a last minute 1 way hop with only a personal item (i.e. small back pack). I will never book this airline again... Very similar to Spirit (which they are now partners with) which is awful. Again never fly this airline... not even in an emergency. Spend the extra seriously.
