Hmm 7x or 5x.. that is a good question.

I know that the Business1 flights follow the standard mealtimes.

2) Mainline & Business 1 flights over 2.5 hours: F-Cabin can expect meals according to the following scheduled flight departure times.
0500 - 1000 Breakfast
1001 - 1059 No Meal Service
1100 - 1300 Lunch
1301 - 1559 No Meal Service
1600 - 1900 Dinner
1901 - 0459 No Meal Service

When "No Meal Service" is mentioned, you'll usually get a fruit and cheese plate.

And, call UA rez for final answer.
