Used SEN before, it was a real WOW in terms of getting through security and to gate in no hassle compared to other places. However getting to/from airport is a real pain, getting stuck in jams is a standard feature. With regards to airlines operating not a great deal of choice and guess under current circumstances not a lot of improvement in sight. Looking at my local airport (NWI) don't know why but I can see a déjà
vu!
