Cheap Flights from Milwaukee to Phoenix from $70

Airlines don't allow to select seats unless we pay extra at checkin and alot random seats towards end of the plane since we donot pay extra. Suprisingly first half of the plan was empty as noone probably paid extra and every one was crammed in the rear end of the plane. In short airlines make us feel very bad about puschaing the economy class tickets and indirectly humiliate during checking process by not allowing to select a seat
