Hi I have been traveling from chennai to kolkata in Indigo airlines and took the middle seat from right wing. You will face problems in connecting to air hostess because she will first ask the left most or right most sitting with you I dont know what is there psychology. Check in counter is fine and well managed but if you carry more laguage then you have to pay huge amount. I already paid 4000 for my laguage. Seating in domestic airlines are congusted for fat people and everytime I reach I found some garbage under my seat or in the bag in front of seat staff are not taking care of this things in connected flight . They will not give anything in free except water and smile. Sometimes siting in middle can make you think is your armrest belong to you. Sometimes pilot or co pilot will not warn you the changing pressure and you need to absorb those hell situations. They are not punctual.
