Aerospace Law would be 6.5 years of unadulterated pain.
You'd spend longer in your undergrad than you would have at high school and all of the subjects beyond 1st year would be intensely difficult and require a lot of hard work and effort.
If you're game for the challenge, then go for it.

As for Aerospace/Comm it's a popular choice and opens many doorways in the job market. THese days a LOT of eng/comm graduates are taken for management fast-tracking programs in companies due to the heightened problem solving skills learnt in an Eng degree.
