If you acceptable an airline's aboriginal boarding criteria, you mightiness not request to wage for the perk.

Travelers tin sometimes bargain aboriginal boarding arsenic an add-on, either erstwhile you bargain the formation oregon arsenic your question day approaches. Sometimes it's bundled with different extras, too.
