This is really evident when I fly on SouthWest out of San Diego or Oakland where there isn’t an airline club to be seen. Its enough for me to sometimes even fly American Eagle down the coast from San Jose sometimes because at least with an AMEX Platinum Card or my HQ Network Access privileges I can score “free” admission to the American Airlines Admirals Club, which has amazing WiFi and power to spare.
Oh and San Diego Airport still has lousy WiFi even if it is free.
