I am used to having wifi on the majority of my flights because Delta flights have inflight wifi on the majority of their flights. When I fly other airlines I am not so lucky and often don’t know if I will have wifi until I get on the place. American Airlines just rolled out this AA wifi widget. All you need to do is put your flight number in and click “find wifi” within 24 hours of your departure.
Its a handy little widget and I have simply bookmarked it on my smartphone for future use. They have a mobile site and will redirect to it on your mobile for ease of use.
