Plymouth is a nice little airport with friendly staff. Not much point in arriving too early - the check-in does not open until an hour before your departure. The cafe is just by the check-in and there is a further landside lounge with the aforementioned free internet. There is just the one airside gate so if there are two flights at once you have to take your turn. Once through security there is a soft drinks vending machine but no other catering. All the seating areas have views over the apron. Everything seems to happen efficiently and with that personal touch that is lacking with other larger airports.
