To finish, temporarily, the set of basic confusables in English, let’s look at the following words: travel and trip (as nouns).
According to the brand new 5th edition of the Longman Dictionary of Contemporary English, an authoritative dictionary for advanced learners of English,
1. travel (or traveling) is used to mean the general activity of moving from place to place. It’s an uncountable noun.
Air travel is becoming cheaper.
Her work involves a lot of traveling.
2. trip, on the other hand, is when you go on a short journey, or a journey you do not usually make, and come back again. Use this when the emphasis is on where you are going or why you are going there. It’s a countable noun.
my first trip to the States
a business trip
