But the math favors E175 in terms of upgrade chances. (F:Y ratio)
E175 1:5.33 (12F64Y)
A320 1:11.5 (12F138Y)
B73G 1:9.5 (12F114Y)
B738 1:10.4 (16F150Y)
B739 1:7.95 (20F159Y)
More Y seats also mean more elites in Y competing for the same upgrade. But mostly depends on which fare you purchased and what time of day/week you're flying. I can only recall 1 missed upgrade on E175 for me in the last 5 years (on a Friday evening STL-EWR).
