The video I did not see since it has been removed, but I'm sure there is more to the story we are not being told.
As for DAL and servicemen, don't forget about this one:

Plus during the holidays, DAL at ATL, MSP and I think DTW have an area where traveling service members and their families can go to wait for their flights, get free food and drinks and watch some TV. It's not a lot, but it is something.
Also, as someone who is on mil leave from Delta, they are a great employer when it come it mil leave and have always worked with me.
As for other airlines and mil baggage fees, in the past I've flown on UAL and SWA on a mil ticket a couple of different times with chem gear, pro gear, etc and was charged a fee since it was over 50 lbs, filed it on the voucher and got the money back. One time SWA let me slide since it was 2 lbs over the limit. As was said in this forum it is a business and all the airlines cannot fly 1000's of lbs of heavy bags for free!
Finally, I hate that all the airlines (but SWA) nickle and dime the pax for bags under 50 lbs and most charge you for food on the longer haul flights. I hear so many pax complain about it and they would rather have it lumped into the price of the ticket. But I guess we have all these travel search engines to blame for that!
