Im confused on this point...first you say no entertainment and no wifi, BUT that there was an app to download...if they had the GoGo (whatever the streaming app is called) offered, then clearly there was entertainment and/or wifi? Something may have broken and thus the wifi was out? Which is unfortunate but given that these pleasure routes to Mexico are such are usually not the 'newest' planes and as was mentioned, they cant fix things like this at small airports. While its a bummer, it happens, you can file a complaint and get some compensation, but lets be honest....no one gives a hoot that you're gonna blast them on yelp or instagram or whatever.
