Thanks so much everyone, and for the number too.
I had to leave voicemail with BA, but I also contacted Virgin, who e-mailed me out a packet, which seems pretty helpful.
Based on the fact that the measurement of the cage, volumetric, is heavier than the animal, it seems that it will cost a minimum of $1500, but only if the XL cage is big enough for a springer, I guess I need to measure her.
I am sooo stressed!!
Thank you!!!
