Uncertainty around the future of Avianca Brasil is growing as the company faces financial turmoil. Citing an inability to strike a "friendly agreement" for renegotiating aircraft leases the carrier sought protection under Brazilian bankruptcy laws this week. The move comes on the heels of lessors seeking the return of 11 aircraft for non-payment. The potential loss of aircraft is bad for the company and for its passengers, of course. It could also see a long-stalled inflight connectivity deployment finally terminated.
