There is currently F open on every UA flight on Weds 7/12 EWR-TPA except the first morning departure (0630). The others are all J1 or J2 with even a J3 on the late departure. I know this isn't helpful to get out today or tomorrow but those are the options at the moment.
For tomorrow there's J1 on EWR-MCO at 1713, 1830 and 1930. I agree with others suggesting an MCO flight and driving. Or you could also do SRQ although those are all zeroed out for Tuesday.
