Oh and if a class date or even interview comes along please pass on your stats and thoughts on what got you selected for the interview. Thousands of people are trying to figure that piece out.
There is no use making decisions that aren't in front of you now. Of all the pilots I know, I think the ratio 100:1 describes pilots that still don't have legacy interviews (anywhere) to pilots that have to worry about a choice between carriers. Good luck though!
That said I'd go United.
