There are three basic types of commercial real estate leases. These leases are organized around two rent calculation methods: net and gross.. The gross lease typically means a tenant pays one lump sum for rent, from which the landlord pays his expenses. The net lease has a smaller base rent, with other expenses paid for by the tenant. The modified gross lease is a happy marriage between the two.
The Transportation Security Administration agrees with it, but airlines don't. For instance, American Airlines advises passengers to be at the airport two hours before flight time for international departures and 90 minutes for domestic flights. Also, there's an exception for flights to certain overseas destinations, which require that you check in earlier.
