| During my recent vacation to Colombia (and Peru), I arrived at BOG twice internationally, once domestically, and departed internationally twice and domestically once. The arrival process each time whether Puente Aereo or Terminal 1 was efficient, hassle-free. Departure domestically at Terminal One was slow; international departure towards LIM was slower; international departure to USA was absurdly ridiculous, slow, inefficient, rude and inattentive service. The main culprit in this negative experience is the unfriendly ticket agents at Avianca. We arrived about 2 hours, 45 minutes before departure, immediately, queuing in the economy check-in line. There could not have been more than 60-75 persons ahead of us in line; there were 9 agents working the counters; yet it took 1 hour 45 minutes to get to the counter! That averages over 12.5 minutes to process each passenger; that is slow. Most of the staff could be seen checking their cell phones, texting. The only staff exhibiting any urgency were the once calling for passengers for Quito, San Salvador and Guatemala City that might miss their flight. Once we checked our luggage and received our boarding passes we needed to go through security, emigration, hopefully get a bite to eat and maybe buy a last minute souvenir. In security and was seated while my mom and I (Colombian-born USA citizens with pre-1990 USA naturalization certificates) were detained and hassled. Emigration officer insisted on reading every single immigration/emigration stamp in my 10-year old passport! We exited security with barely 15 minutes before our flight was called. The food court at BOG is close to security but far from our gate. From our trip to LIM we knew that the rest of the eateries were few and blah. I managed 2 quick purchases including water and chocolate to hold us over until in flight meal. If you fly out of BOG, avoid Avianca! I used to love this airline, but their BOG staff is worse than CCS, AUA, SJU, and other hassling airports. I have been in and out of BLR and BOM airports in India and they beat BOG with better customer service, less hassling. As a departing comment, we complained to both Avianca and to El Dorado through social media. Not even a response, apology or explanation.
